Observer
Name Doris K
Experience Level 2/5
Remarks The time is approximate. I witnessed with my husband then went inside to do some reading and realized this was a bolide we had seen, didn't realize how rare it was and how much attention we should have paid to the details. Hoping others have better notes to share
