Reports Report 3962c (Event 3962-2020)

Observer
Name Cameron B
Experience Level 1/5
Remarks I 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.
