The light curve is dominated by 4 different brightness law settings separated by the red lines, at number 4, the outburts of the comet are observed, estimated in 2 magnitudes, I have made an adjustment of polynomials of degree 1, to adapt The light curve to the 4 different settings.

My last analysis of the ccd-visual light curve, reduced magnitude vs log R, shows 2 semicurvatures in the law of brightness of the comet (in R = 5 au and R = 2 au), DJ 550 and DJ 800, something totally new Which he had not seen in a light curve of a comet, with an upper envelope and a lower envelope in the ccd data, coinciding with a modulation in the law of brightness of the comet. My analysis shows a total of 603 ccd and visual observations, the largest light curve of this comet performed, note that the visual observations show greater dispersion and higher brightness, the magnitudes ccd shows greater clustering in the data. Attached link of my last analysis
