update light visual curve of comet C/2014 Q2 LOVEJOY ( Analysis IV )

Update 27/12/2014 Analysis of the light visual and ccd curve of comet C/2014 Q2 LOVEJOY based in 567 observations from COBS , comet obs , LIADA , observadorescometas .

martes, 16 de diciembre de 2014


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 .

Update the light visual and ccd curve of comet C/2014 Q2 LOVEJOY ( Analysis II )

Good notices from this comet , continue show high rate of increase of brightness based in my personal calculates and personal analysis from 66 visuals observations and total of 354 ccds and visuals observations from Comet Obs , ICQ , LIADA and observadorescometas group , the absolute magnitude is m0=+2.5 and activity index is high comparate others comets n=10.3 and power law R^(-10.3) , the probability of maximum visual magnitude in T-20 days is m1 ~ +4.1 , the visible naked-eye and easy for binoculars .

Update Analysis Light Curve C/2021 A1 LEONARD A1

 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 ...
