NEW UPDATE LIGHT VISUAL CCD CURVE C/2014 Q2 LOVEJOY ( Analysis III )
Based in 511 observations ccd+visual of comet from MPC database , Comet Obs , LIADA , and observadorescometas , update the new light curve of comet C/2014 Q2 LOVEJOY , continue fast increase of visual magnitude and probable state of outburts , my personal analysis indicate several possible outburts for this comet and lack confirmation , the activity index continue high n=10.3 ( 15/12/14 ) and absolute magnitude m0=+2.5 in r = 1,4 au . if you continue this rapid increase in brightness could have magnitude +4.1 in January -2015 , the Afro production is high rate actually ~ 4.200 cms ( From Cometas Obs data ) , dust rate production is typically of great comets , the comet masses computed for C/2014 Q2 , in comparison of comet 2P/ and 10P/ . The possible calculates active surface areas f > ~ 2.4 for this comet . The pre-perihelion formula general calculated is based in 93 visual's observations , thank all's visuals observers , great job .
Comet C / 2021 A1 Leonard shows at the moment with 272 ccd observations a linear fit in its light curve, the provisional photometric parame...
