I performed multiaperture photometry of this comet by APER.pro:
Radius of aperture 0 = 1.0
Radius of aperture 1 = 2.0
Radius of aperture 2 = 3.0
Radius of aperture 3 = 4.0
Radius of aperture 4 = 5.0
Radius of aperture 5 = 6.0
Radius of aperture 6 = 7.0
Radius of aperture 7 = 8.0
Inner radius for sky annulus = 15.0
Outer radius for sky annulus = 25.0
