Analysis of the light visual curve of comet C/2011 L4 PANSTARRS
Hi , recent analysis of the light visual curve of the comet C/2001 L4 PANSTARRS based in total of 43 visuals observations from Comet Obs , observadorescometas yahoogroups.com and Cometas LIADA , the provisional photometrical equation is m1 = +1.9 + 5 log ( delta ) + 12.8 log ( r ) , and photometricals parameters resolved by expert analyst of the light visual curves of comets author , J.P.Navarro Pina , m0 = +1.9 and activity index is n = 12.8 , provisional predicted maximum magnitude in the perihelion of ~ -4.0 , the brightness of Venus planet , this analysis is very preliminar .
