Thunderbolts points to other comets, Holmes, Haley, Linear, and Schwassman-Wachmann 3, had experienced the same situation related to flares that were prevalent over the years that caused the same reaction as Eleein due to electrical properties of the suns actives.
Just a note that apparently there is a "Quadruple outburst of Comet 29P" going on. And that it's at its brightest for probably 40 years.
The unprecedented behaviour of Comet 29P/Schwassmann-Wachmann continues.
A plot showing the behaviour last night is on the MISSION 29P webpage.
The comet may be undergoing multiple outbursts each subsequent event triggering the next.
Trying to fit what we see with past behaviour, it appears we have had at least 4 outbursts summarised as follows:
Outburst at 2021 09 25.340 +/-0.005 16.90R => 14.43R Intensity ~1
Outburst at 2021 09 26.15 +/-0.12 14.45R => 13.73R Intensity ~1
Strong outburst at 2021 09 26.98 +/-0.05 13.75R => 12.40R Intensity ~5
Very strong outburst at 2021 09 27.68 +/-0.06 12.40R => 11.25R Intensity ~12
The intervals between these successive events is about 20, 20 and 17 hours.
As of 2021 September 28.25 UT, the coma appears to continue to intensify slowly.
