UPDATE THE LIGHT VISUAL CURVE OF COMET C/2011 L4 PANSTARRS

Updating the light visual curve of comet C/2011 L4 PANSTARRS , based in total of 81 visuals magnitudes , ( note : only visuals magnitudes not ccd's ) , recopilated from lists of yahoogroups.com , Comet Obs and observadorescometas , obtained the next photometricals parameters magnitude absolute m0=+2.3 and activity index of n = 12.2 , the result photometrical visual equation : m1 = + 2.3 + 5 log ( delta ) + 12.2 log ( r ) The author of this analysis is J.P.Navarro Pina , administrator of list of observadorescometas and investigator of astrophysical cometary , the preliminary results for the perihelion max. magnitude of m1 = -4.0 .
