RemarksThis is a report from my 3 kids on their way to the bus stop. They called immediately on the cell phone and were pretty spooked. they see falling stars and we have a telescope so they have watched they sky for years. They are ages 11-15. I didn't find anything online to find out what it was but i found this web site and thought i would report it and see if you guys have any other reports or an explanation. Thanks
