ball of light shot across sky - lit up like daytime at 9:15 PMI was driving home from work when suddenly the sky lit up with this fireball or ball of light shot over the horizon from NW to the East - towards montana. It was like daylight for about 30 seconds. I could see across the prairie. I found out a day later that another had seen the exact same thing that night.((NUFORC Note: Date is approximate, but we have assigned a date because of other similar reports from November 14, 1998.
