Analysis of the reduced light curve of comet C/2014 Q2 LOVEJOY , Water rate production , Fraction active surface , Masses estimated .
I estimate the masse for a comet C/2014 Q2 LOVEJOY , the diameter of the nucleus , maximun water rate production in the perihelion , and active surface fraction , this calculations is based in 3.200 observations from database MPC/IAU , and personal elaborating light visual and ccd curve of comet along time of near 1 year of work , the down graphic is reduced for geocentric distance in y axis , and x axis the heliocentric distance in au , this work is new analysis for comet C/2014 Q2 LOVEJOY and contain great quantity of observations . The introduction physical's parameters of Mn ( masse) , log Q(H2O) , f , and D , the results , is Max log Q(H2O) = 10e 28.58 mol s-1 ( 1000 kg/sec. ) , log 10 Mn ( kg) = 11.6 , D = 1.0 km , f = 2.3 .
