SOHO Comet Discoverers' Totals

 

Last updated: September 03, 2010

Current totals: 1901

This table lists of total number of SOHO comets, including SWAN discoveries. Note that only the comets, confirmed by MPC and reported on MPECs or IAUCs, those internally confirmed by SOHO personnel and granted a "SOHO number" when still awaiting permanent designation as well. Refer to Sungrazer Web site for reports and astrometry. Please notify me about the errors and your disagreements.

Next week (probably Tuesday) we have an exciting announcement to make,
so please "stay tuned"!  And don't forget about 'SungrazerComets' on 
Twitter -- I try and put interesting comet-related information on there
a few times per week.

Please note that SOHO-1891 was reported to the SOHOHunter chat group.

As you have all probably realized, SOHO is in its 'keyhole' right now 
so data gaps will become increasingly frequent.  I still don't know the 
schedule for LASCO being turned off/on for the SOHO roll.  I'll post 
it when I do.
--
Not long to go until SOHO-1900... Good luck to everyone hunting for
it!

It has been too long since I last posted a set of these to the
reports page!  These include all recent reports to this page but not
five archive claims made by Jiangao Ruan to the SOHOHunter page.  I'll
look at those once we pass SOHO-1900.
--
I should note that the above list is courtesy of Michal Kusiak, who is
still helping me out while I catch up on recording/measuring the 
backlog.

Notes:
XC75 - we have only 4 consecutive images, another positions don't matched well
XC76 - due to not enough number of images(positions)

SOHO-1823:
Karl said, that the track of Masanori's positions does not align well with my report. So he think that credit must go to me.One of the Jiangao's archival claims will be SOHO-1830. Another archival comets I will post soon.

Karl decided, that Masanori will get a credit for one of two fragments dicovered in LASCO C2 images from Feb15 (1806), because his first post for 1805 included only two positions. SOHO-1802 (overlooked by me in last discovery list) looks to be real and it is visible in additional HI-1A images.

Hi Everyone,

Here is the list compiled by me and Karl for last SOHO and STEREO Comets. Apologies for delay, due to waiting for another SOHO milestone. :) Thank you to Alan to last post about comet from Feb6,2010. I hope that everyone agree and a SOHO-1800 winner is: Masanori Uchina :) I don't see nothing convincing between 1799 and 1800.

Few weeks ago Karl submited SOHO and STEREO astrometry data to MPC for Masanori's SOHO report from Nov5,09 16:52:47, and Brian Marsden confirmed that it was a real kreutz comet visible in C3 images (before data gap) and HI-1A also.

Please note that Jiangao Ruan and Alan Watson will get a joint-credit for STEREO 29 and 30. There were some problems with STEREO-Hunter group connection. Jiangao submited his report at 08:40 but it showed up in STEREO-Hunter 9 minutes later. Alan has submited his report at 08:46 and he (and nobody else) didn't know about Jiangao's claim. So, we think that the co-discovery was the best way.
Also, Karl said that second object reported in msg #1197 looks to convincing noise.

Please e-mail, if you find any mistakes, or if you have any questions.

First, I have 'sad a bit' information for Rainer. 
I asked Karl yesterday for opinion about his possible fragment trailing close to known Kreutz, unofficial confirmed by me few days ago.
Karl decided that he can't confirm this comet. The fragment that Rainer reports (Dec 23 2009 19:00:24) is too close brighter comet. 
Also, Masanori's comet is very likely to Alan's HI-1B (STEREO-22), so at this moment credit will go to him.

Congratulations for Hanjie Tan, on his first SOHO comet discovery!

Finally, I have made a list for few archival claims submited in past, which I'm sure that there are real.

These include every archive claim I have seen/received up to about an
hour ago. They're numbered by image dates, not the order in which they
were reported.  I figured it didn't really matter either way.  I can
not confirm any other archive claim I have, and am not prepared to
allocate 'x-comet' status to objects that are, at best, marginally
convincing noise.  We don't want the 'x-comet' list becoming larger
than the discovery list!

Please note the minor corrections to #1686 (date and camera change).
Many congratulations to Bo Zhou who has now found over 150 comets (
and also got SOHO-1700 in my last set of confirmations)!

XC72 was not the Kreutz visible in HI-1B on Oct07 (that was 1707),
and there was no more LASCO data for that time due to the SOHO/EIT
"shutterless" mode, so it's an x-comet.  
--
XC73 was strange. It almost looked like a tiny Kreutz but its 
appearance was a little inconsistent and the positions did not quite
line up the way they should.  I can't confirm it, but I don't want to
throw it away either.  Hence it gets to be another x-comet.

I have finally gone through all the archive reports I have and will
post the results later today.

I bet you all thought I'd forgotten about you, didn't you??  Many
apologies for being absent -- it has been a very, very busy year for
me.  
--
These take us through September but do not include the (*many*)
archive claims I still haven't looked at.  I'll deal with those once
I get up-to-date, so if you have any you haven't sent me, please do so
(there's only so many times I want to have to go through the
archives...)
--
As always, the reports marked * are SohoHunter reports (timezone=GMT?). 
I still can not confirm Bo's 2003 x-comet, most recently reported on
Sep08,09 13:00:10.  I can't see anything in C3 at the reported
positions.   Finally, I can only see SOHO-1703 in C2. 
--
Please let me know of any errors/omissions within the next day or two
before I tackle October reports. Thanks!

Congrats to Rainer and Bo on their recent Non-Group finds!  It's
very unusual for us to get three of them in such a short period.
--
Sorry I forgot to inform you all about SOHO.  If you read the 
'Daily Meeting Minutes' on the SOHO website, you'll see that SOHO
went into ESR (Emergency Sun Reacquisition) due to an onboard
anomaly.  Everything seems to be fine, but they always proceed
cautiously in these situations.  It looks like LASCO will be
recovering some time today, but I do not know when exactly.

Michal's report from May03,09 10:32:15 M.Kusiak is XC71 because of 
data gaps. Also, I can not confirm the fragment reported at May27,09
05:48:25 -- I can see what was reported but it's just a little too
close for me to call it something separate.
--
So these confirmations bring us fully up-to-date. Now I suppose I
had better start measuring some of them...

I can't confirm Tony's report from Apr13,09 00:07:36.  I also can't 
confirm Jiangao fragment report from Apr20,09 19:46:55 -- I see what 
he's reporting but I think it's just part of a faint/lumpy tail.
As you can see, I have added Yi-SWAN to the list since it's a SOHO
co-discovery.  I couldn't get convincing and/or well-aligned positions
for XC70, hence it's an x-comet.
I am currently working on May confirmations. Sorry about the delay
in comet-related work lately -- I'm going to be able to focus on it
for most of next week, so I'll make up some ground.

SOHO1609 (B.Zhou) was reported to me by email before it was reported
to the 'SOHOHunter' chat group by other comet hunters.
-
It looks like SOHO-1619 is our 100th Meyer-group comet.  Many 
congratulations to both Eryk and Maik!  Speaking of which... please 
note that I am confirming Eryk's *follow-up* claim for Meyer #100 -- 
NOT the original claim.  That's because the original claim did not 
follow the rules!!  Eryk is lucky that no one else reported the 
object in the meantime... Everybody repeat after me: "Only C2 Kreutz
can be reported with two positions". Thank you! :)
-
Finally, I should have mentioned this when I did confirmations in 
January...  According to my records, SOHO-1600 was Hua Su's 200th
SOHO discovery!  Many congratulations for that great achievement!

I have denied Hua's non-group claim from Dec30.  The C3 positions do
not work at all with the C2s.  Also, the C2s are close to being OK
but not close enough -- and they should be perfect for such a well-
defined object.  Finally, it appears from nowhere and is too bright,
too quickly, and then disappears again.  So I'm confident it is just 
well-placed noise.  Unfortunately, this does mean that by my count, 
Hua currently has 199 SOHO discoveries...  Hopefully #200 will come
soon, but in the meantime, congratulations for finding SOHO-1600! :)
-
I accidentally forgot Michal's Kreutz from Dec25, so it got added
to the end of the list (I needed the HI-1A positions to be able to
confirm it, but forgot about it until I was nearly done with the 
other comets).
-
Please remember that ONLY C2 Kreutz claims can be made with two 
positions.  All other claims must have at least three positions. If
you fail to follow this rule, you risk losing credit for an object.
Credit is always given to the first person who most closely followed
the rules.  And please remember to retract your claims if you can't
provide at least five positions for the object.

These confirmations cover us to Dec 18 2008 03:51:39, inclusive.
Please let me know if you think I have forgotten about your report
or if you think I have made a mistake.
Note that SOHO-1581 and SOHO-1582 were released on an MPEC this
morning.
Oh, and don't forget to check out the new article on the "Latest
News" page.  Congrats again to Alan, Maik and Rainer on the recovery
of P/2003 K2!

October has been busy! Well done everyone! I think Hua Su is getting 
very close to 200 comets now, Rob Matson is edging towards 100, and
Rainer Kracht is nearing a million. . . (well, almost) :)
--
Please note the following: Objects marked "*" were reported via email
and/or SohoHunter group. Times are US Eastern (EST). Due to a data
processing and transfer problem, I do not have easy access to the
data for Sep28 (SOHO-1534), so for now I am going to trust that it is
a real object.  (It's appearance in C2 certainly adds weight to my
decision).  As soon as I get that data in another week or two from
now I will, of course, verify it.  Finally, I do not have the data
for today yet, so I have not checked reports from Oct 30 2008 22:20:15
onwards.

Please email me with any problems, questions, corrections, etc.

Oops!  It looks like I got my timezones confused with one of my
recent confirmations. SOHO-1525 should read:
1525* Sep04,08 22:20:00  J.Ruan         C3   Kreutz  Sep04-05,08
Many apologies (it was a very busy time for me...)
--
On a separate note, I hope you all like the blue text for comet 
confirmations.  I think it makes the page *much* easier to read and 
interpret.

I don't think I missed any reports but if you think that I have
forgotten you, please email me and ask.

Something I meant to mention yesterday but forgot... When you submit
comet reports, you will see some kind of an error message at the bottom
of the 'thank you' page.  Please ignore this message!!  As long as you
see the "your report has been logged as..." message, then you are fine.
I will try and fix that bug eventually but it's a low priority right
now.

Of course, SOHO-1517 = C/2008 O1.  SOHO-1516 will be released on a 

later MPEC (tbd) -- it's just an "ordinary" non-group object, though.

I believe that SOHO-1522 is Zhijian Xu's first SOHO comet -- many

congratulations, Zhijian!!

Wow -- what a busy start to July!  Some nice comets in there too, 

especially the non-group objects.  Great finds!

Many congratulations to Bo Zhou for being the sixth comet hunter to

reach 100 comets!! Well done!

--

As some of you may have seen on the "comets-ml" Yahoo! group, I am

going to be supporting Alan Hale in his quest to observe visually a 

sungrazing comet during the August 1st eclipse.  I would just like

to mirror his request for you all to be extra vigilant in your SOHO

comet-hunting in the couple of days leading up to the eclipse.  If 

any of you will be in a position to observe the eclipse, I encourage

you to be on the watch for sungrazers! (Warning: pointing telescopes

at or near the Sun, eclipse or not, is extremely dangerous!!  Please

be careful!)

As always, feel free to email me your questions, comments, 

compliments or complaints.

Well done to Michal for finding so many comets recently, but the

big congratulations are reserved for Rob and SOHO-1500!! Fantastic

stuff!  Thanks to everyone, too, for all your efforts.  I hope you

all stick around for another 500 comets! :)

All,

We appear to be having intermittent web server problems.  Please be

prepared to email me your reports (and, optionally, post them to the

SohoHunter group).

Also, since I'm posting, I'll give you a handful more confirmations

too:

I have actually got all confirmations finished up to the most recent

report... but I have decided it's more fun if I keep them secret for

now! :)  You will get to see them all once we've found SOHO-1500 

(which, at current rates, could be by the end of next week!).  The

only thing I will say is that, in addition to the above x-comet (we

had a LASCO problem that day so data is lost), I can not confirm the

Meyer comet reported by Rainer at Jun 09 2008 08:30:45.  It was just

well-placed noise.

--

Please email me with any questions, problems, etc. Oh, and good luck

everyone!

A predictably busy month.  Many congratulations to Giuseppe for 

finding his first two SOHO comets!!  Also, well done to Jiangao and

Michal for finding a total of 12 comets between them this month!

--

So clearly we are heading towards another big milestone -- 1500! (I

can't believe we are here already!).  As is my policy for events

such as this, once we reach #1490 I will suspend recording "archive"

comet discoveries until after 1500.  So if you have any archive

claims you plan to submit, do it now or wait until after 1500.  My

definition of "archive" data is a bit fuzzy, but basically any

images that have been readily available for more than ~24hrs could

be considered archive.  Email me if you want more clarification.

First, I disagree with C3 positions given for SOHO-1454. I just

can't get them to work at all (and I can't see anything there!).

--

Second, Jingao and Michal's comet from Apr23 will have to be an

x-comet, as the next few hours of SOHO data came from EIT only.  

Also, while looking at that object I saw what looks to me like a

leading component, though I'm not certain on it since we only have 

two images. My positions are as follows:

       XC65  C2 Kreutz  Apr23,08, (0,0) lower-left

       4/23/08  14:35  261,40

                14:55  270,54

I'm confident enough to give it XC status but I would have liked

at least one more image as it isn't a "typical" looking Kreutz

--

Finally, many congratulations to Eryk Banach on finding his first

SOHO comet!  Also, at 14yrs old, I think he is one of the youngest

SOHO comet discoverers.  Well done, Eryk!

approaching SOHO-1500!!

I should also mention the following comets:

SECCHI-001  (C/2008 D1)  A.Watson  HI1-A 

SECCHI-002  (C/2008 D2)  A.Watson  HI1-A

SECCHI-003  (C/2008 D3)  A.Watson  HI1-A,COR2-A,COR2-B

SECCHI-004  (C/2008 D4)  R.Kracht  HI1-A

Alan also has another couple of reports pending that I need to check

over.  Many congratulations to Alan and Rainer!!

It is my intention to merge the SECCHI and SOHO comet programs -- by 

which I mean start including SECCHI comet information on the 

sungrazer website.  That will happen later next month.  In the 

meantime, I am going to begin measuring the SOHO-discovered comets

seen by SECCHI instruments.  Hopefully the multiple viewpoints will

give us some fantastic orbit determinations, such as that for 2008 D3!

That's the only one I can confirm in the recent lot. I was not at all

convinced by Tony's Jan 8th claim. Too slow, too inconsistent in

shape and brightness, and I couldn't see it in two of the positions. I

also could not see anything in C3 reports made by Rob and Bo around the

same time.  

--

You may have noticed that I am running quickly through the backlog of

astrometry measures. For now I am going to stop at SOHO-1423 until we

have a better data product available. I would have liked to have 

measured 1429 (above) but we have a big data gap on the 15th. We will

recover that data in the LZ data product, but that will not be processed

for another two or three weeks.

First, congratulations to Parrish for finding his first SOHO comet!

At the other end of the scale... enormous congratulations to Rainer

Kracht for becoming the first person to find 200 SOHO comets!! It is

an extraordinary achievement, and a well-deserved one for the many

hours Rainer has dedicated to SOHO comet hunting. (It's just a shame

it was a Marsden-group object and not a Kracht-group one -- that 

would have been very poetic!) :)

--

I'm not sure what to make of Arkadiusz's object. I think it is a 

Kreutz (group II), but it's certainly well off the usual path. Also, 

Rainer's most recent Meyer object seemed to have a lower inclination

than the nominal track, but I could be wrong.

--

Once again, I hope you all have a wonderful New Year, with plenty of

SOHO comet discoveries!

Also, congratulations to Bo for finding SOHO's 1400th comet!!

Way back on Jan20,2004 (12:46:38) I confirmed SOHO-700 and made the 

comment "let's hope for 700 more". I'm not really sure if I actually

believed we could reach SOHO-1400, but I should have had faith in

the remarkable SOHO satellite and the extraordinary dedication of

all of you SOHO comet hunters! So it is with far less hesitation

that I now say "LET'S HOPE FOR ANOTHER 700 MORE"!!!! :) Thank you

everyone for your continued contributions to this project -- every 

new comet you find is making history!

Bo's C2 Kreutz claim was too inconsistent in shape/brightness and was not

visible in as many images as I would like. Therefore it is an x-comet.

There
were one or two 'confirmed' reports that I could not confirm. If you have

any specific questions about your reports, please feel free to email me.

--

You may have noticed that in the past two weeks, I have gotten the

"official"
comet measurements sent off and so -- thanks to the hard work and

patience of  Brian Marsden -- we're now pretty much up-to-date. I'm going to be

tied up  with something else for the next couple of weeks, but I think we are

in good 
shape right now. Please continue to keep the noise down to an absolute 

minimum -- it's been very good lately, so thank you!

do not line up with Hua's C2 Kreutz. In addition, it is not visible in

object as bright as that should have been). So it can be an x-comet for 

now.

--

Going back to P/2007 R5... I have two choices regarding SOHO numbers. I

can either vacate the SOHO-661 spot for the next archvie Kreutz to be

reported, or I can just stick with SOHO-85=661 and leave it at that. 

(Note that I am NOT willing to reduce the SOHO comet number of comets 

662 through 1359!). I think I will probably vacate 661 and give discovery

credit on the web page to Terry, Kazimieras and Bo. That sound OK to 

everyone?

look at the others yet. I will be away all of next week so I'll

These complete confirmations for June 2007 and the archive claims

from May. Please let me know if you think I have made a mistake or

forgotten to check your report. I'll start checking July later today.

You might have noticed that the realtime gifs on the LASCO website

were not updating regularly. It was a very odd bug that took a long

while to track down, but I have it now and the LASCO data should be

updating on its usual schedule again. Sorry for the inconvenience.

Many congratulations to Bo Zhou for flying past the 50-comets mark!
Unfortuntately I was unable to confirm several other claims he made,
mostly because the objects were at the level of background noise.
This included the Kracht-group comets he reported.

Well March proved to be a very quiet month (which was good for me

since I'm so busy!). I think I have checked all the reports but let

me know if I missed any. It should be noted that most, if not all, 

of the above comets were observed in the SECCHI HI-1A instrument --

even Tony's C2-only Kreutz!! Many, many thanks are due to Alan Watson

and Rainer Kracht for monitoring that data. In due course I will

begin the process of measuring the comets in those images

--

I will be on travel again all of next week but should be in occasional

email contact if there are any problems.

Note that Arkadiusz's post of Feb 16 2007 17:33:06 was referring

to Hua's comet from earlier that day. Note also that Tony's 

report from Feb24,07 20:14:04 can not be confirmed -- those were

the only three images we had for several hours.

LASCO doors are back open after the station keeping maneuver, but

they will close again briefly tomorrow for the spacecraft roll.

Wow!! In February 2006 we had a total of 11 comets for the whole

month... This Feb., we have had 10 in the first nine days! Amazing!

Congratulations to all who found comets, especially Masanori who

found his first SOHO comet after only three days as a "registered"

comet hunter -- that has to be a record! Well done, Masanori!

--

I was hoping Hua's non-group comet would survive a little longer

than it did. Oh well...

As you can see, Rainer's unusual comet got promoted from X-comet

once I stopped treating it as a Kreutz. I think it must be a non-

group object -- it just doesn't move like a Kreutz in my opinion.

--

There seems to be a resurgence of non-group comet claims. Please

think carefully before you post these. We see very, very few non-

group comets, especially in C3. Otherwise the report form is 

looking quite junk-free, so that's nice -- thank you!

Several things to say... First, sorry Rainer but that little Kreutz

of yours just wasn't right somehow. I couldn't get a fifth position

and I just didn't feel 100% confident of it so it is an X-Comet. 

Second, the C3 positions given for Rainer's Meyer-group comet did

not work at all, so that is a C2-only object. 

Third, I will be on vacation until January 8th. Please try and keep

the number of posts down to a sensible figure. I realise that we have

just had a big "comet storm" but we are now heading into January, so

the C2 stream will dry up completely and the C3 stream should tail

off somewhat too -- so I expect the volume of reports to decrease

accordingly!

As always, email me if you have any questions, problems, etc and I 

will answer you when I can.

I hope everyone has a Happy New Year! :)

It looks like the three-position minimum for C3 is working out nicely.

The reports page is much more readable than usual (admittedly the lack

of images has helped somewhat, too...).

Congratulations to Rainer on finding a very tiny archive Kreutz.

The website is a little out-of-date in terms of MPEC links, etc, so I

am going to fix that now. (More MPECs were released today, btw)
