Observer
NameJeff W
Experience Level2/5
RemarksBrightest & longest I've every seen. I was facing roughly North & it appeared a little to the right of Polaris, headed pretty much horizontaly due East through Cassiopeia. Timing is roughly 11:10pm give or take a few mins. I'd been checking on my telescope as was imaging NGC7380, checked the subs this morning but no appearance on any of the frames from around that time.
