BVR photometry of comets 63P/Wild 1 and C/2012 K1 (PANSTARRS)
We analyzed the BVR photometry of the comets 63P/Wild 1 and C/2012 K1 (PANSTARRS) obtained between March 2013 and May 2014, with 0.20-m to 2.0-m aperture telescopes installed in Australia, Europa and USA. We have found R-band nuclear magnitudes H 0 = 16.3 ± 0.6 and 12.52 ± 0.02 for 63P and K1 comets...

The Kruskal–Wallis H-test suggests that the distribution of the color indexes B-V, V-R, and B-R of the objects are similar, indicating some kind of equality between the physical or mineralogical properties of the comas of these comets. |
