Reports Report 3962c (Event 3962-2020)

This report has been linked to the following event: Event 3962-2020
Observer
NameCameron B
Experience Level1/5
RemarksI can’t find anything on the news or reports about this (comet, asteroid?). It was the largest astronomical event I’ve ever witnessed. The comet was very brief but the trial lingered. I would love to know more about what this might be. The comet was very large, probably 1/4 the size of the full moon and glowing. Wondering if anyone else saw this event, as a few friends were with me witnesses as well. I was most likely looking south East.
