Reports Report 2307dn (Event 2307-2018)

Observer
Name Dennis R
Experience Level 3/5
Remarks There was still a lot of daylight left at 8:40pm (20:40), as the sun had not quite yet set Despite all the daylight, this green fireball was very bright. It was the slowest moving fireball that I have ever noticed. I pulled my cell phone out to take a picture of it but... I was too slow getting my cell phone 'ready' to take the pic.
