ANALYSIS OF THE LIGHT VISUAL AND CCD CURVE OF COMET C/2013 US10 CATALINA

Hi all , based in the analysis of the light visual and ccd curve of comet C/2013 US10 CATALINA and recopilation from database MPC /IAU and list of comet obs and observadorescometas yahoogroups.com of 1.210 observations , i analyzed the graphic and data and obtained than the probability of visual maximum magnitude for this comet is m1(max)~ 6.0 for 2016 , my differential analysis of the light curve based on a sum of observations CCDs and other visual and visual only gives the result for only next formula : m1=5.4+5log(d)+7.8log(r) and the poor activity index n=3.1 this result indicate than brightness of comet is a comet that behaves solid object type asteroid in actually heliocentric distance R=1.00 au , this is very typical of the new comets Oort Cloud (e= 1.000322) when they exceed the heliocentric distance of r = 1.5 au brightness stagnation and stifling dust activity and especially the gas is produced, in my opinion this activity remains off and could be reactivated in February …
