Reports Report 2834o (Event 2834-2018)

Observer
Name Jeff W
Experience Level 2/5
Remarks Brightest & 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.
