Analysis Light curve C/2017 O1 ASASSN

Analysis of the light curve of comet C / 2017 O1 ASASSN based on 518 visual observations and ccd of Comet Obs yahoogroups.com, observers comets yahoogroups.com, COBS database, LIADA comet database, it is the largest curve of elaborated light of this comet so far, based on this analysis the comet suffered an outburts in R = 1.85 au which carried it at a confirmed rate of 400-500 cms of dust production based on data from CARA database Afp parameter, this outburts, made up 2 magnitudes ccd to the comet with respect to its average magnitude, in the data of visual magnitude I have not found any indication of this outbreak, the ccd data are of value to know the rate of dust production. In T-60 days, the comet suffered an inburts or brake in its rate of increase of brightness that makes it lower 1.5 magnitudes ccd, in the visual data I have not found any indication of this fact either. The brightness brightening curve of the comet is very slight and the comet is most likely not to exceed a maximum visual magnitude of m1 = + 8.5, but there are more bursts of brightness. The calculated physical parameters of this study are based on the formulas given by Sosa & Fdez 2011. Green line : visual Observations , Red line : ccd observations .
