Reports Report 2123c (Event 2123-2020)

This report has been linked to the following event: Event 2123-2020
Observer
NameAleks B
Experience Level2/5
RemarksThis was captured on a security camera and I noticed it during a footage review. The video has a grainy 4k version, but YouTube is still processing that. No specific audio was noted, though other planes that fly overhead are always heard. A plane is seen 10 minutes later on a path to the Northwest (included in video in case it helps with scale or other investigation). I have never noticed another object traverse the sky visible here at the velocity observed.
