Reports Report 3210dy (Event 3210-2017)

Observer
Name Josh W
Experience Level 5/5
Remarks This is the third brightest and most interesting meteor I have seen and I have spent thousands of doing astronomy observations under the night sky. Two people in our party of four reported potentially hearing a sonic boom a little over four minutes after the event, but I think they may have heard something else, as I was still listening at that point and while I did hear something, it did not sound like the sonic boom that I have heard before.
