ANALYSIS OF THE OUTBURTS AND THE LIGHT VISUAL-CCD CURVE OF COMET C/2013 X1 PANSTARRS
My last and personal analysis of the light visual curve ccd+visual , show the data of recent outburts confirmed for multiples observers , the first notice of alert is one message of Stephen McCann UK in the yahoogroups.com comets-ml the 3.87/Jan./2016, the observer alert increment brightness of m1=+8.5 , the last visuals magnitudes from the data indicate range of visual's magnitudes of 9.5 < m1 < 10.5 , the visuals magnitudes : 8.0 , 8.8 , 8.5 and the last recent 7.9 ( Neil Norman , UK ) in the 3 , 4 and 5 January 2016 . The photometric law visual indicate visual magnitude max. of m1~ +5.0 in 20/06/2016 , based in formula m1 = +2.2 + 5 log (d) + 18.2 log (r) , the power law is high n=7.3 , based in R^ (-7.3) .
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 ...
