ALERT FOR COMET , C/2014 Q2 LOVEJOY NAKED EYE IN JANUARY 2015 ?
Interestingly comet could observe visual magnitude +6.5 in early January 2015, currently ICQ ephemeris put m1 = 12.4 ( 30/10/2014 ), and its visual magnitude observed is m1 = 11.0 ( S.Aguirre Mexico , last visual observation 30/10/2014 ), this -1.4 magnitudes brighter than theoretical, so which could reach maximum brightness for early January 2015 m1 = + 6.5, in the limit of visibility with the naked eye, will be observable in the hemisphere in mid-December 2014. My personal preliminary analysis of the light curve of this comet indicates a high rate of increase in brightness and a high slope in the brightness law (S. Yoshida n = 6.0) this indicates an activity index alo gas and dust nuclear level, in fact the cCD images show strong central condensation typical of bright comets, my personal opinion is that we have a good comet for December and January 2015.
My second analysis of the light curve of comet C / 2021 A1 LEONARD, indicates in T-300, a stagnation in the rate of increase in brightness ...
