This is the largest bolide I’ve ever seen. There were 9 witnesses with me. It looked like it came straight down. Jupiter was slightly west of it and Saturn was slightly east. We were stargazing looking at the northern lights and a possible “Steve” observation when it lit up the entire sky like daytime.
