Reports Report 9578a (Event 9578-2022)

Observer
Name Chris W
Experience Level 2/5
Remarks My first guess was lightening based on brilliance, but there was way more of a terminal effect than I've ever seen, and color was wrong. Other possibility is maybe a giant transformer explosion, as we were seeing progressive power failures in the region during snow storma. Haven't been able to find info on it yet.
