Analysis C/2020 F8 SWAN
In my differential analysis, the comet shows 3 different brightness laws with 3 changes in photometric parameters: 1 law R = 0.87 au 2 law R = 0.77 au 3 law R = 0.67 au the equal difference in the variation of the heliocentric distance of the comet from d (r) ~ 0.10 au, with an increase in brightness and later a decrease in brightness, there is an outburts in DJ = + 2450000 + 8965, of approximately 2 magnitudes: d (m1) / d (r) = 2.0 / 0.10 = 20 mag / au My hypothesis is that the comet has undergone a sudden and brief increase in brightness due to an unusual increase in the comet's dust and gas production rates that has lasted approximately less than a week, the brightness production rate should stagnate and continue even steady rhythm without going down.
