Reports Report 3712c (Event 3712-2021)
| Observer | |

| Name | Ryan M |
| Experience Level | 2/5 |
| Remarks | It was not yet dark, it was early twilight and visible. Last night there was a report of a fireball around the same time in Idaho and South of here. I had my camera out because a falcon or kestrel had just flown that direction. By the time I turned the camera on, the kestrel was in a dive. I goy a photo then I saw this bright green, blue orb against the still bright blue sky, not even dark blue sky. I've never seen one this early in the twilight. When I got a picture of it, there are two, one trailing the other. They seemed like cloud level. |
