Observer
Name David H
Experience Level 2/5
Remarks I have been an amateur astronomer for around 50 years. I have never seen such an object before and doubt that I ever shall again. Ironically, I was setting up for some astrophotography at the time, but was polar-aligning my star tracker as I glanced to the East and saw the object streak across the sky from Sth East to Nth East. Quite amazing.
