Yellowish white lights brighter than the north star about 10 miles over the hills in Hagerman Idaho.As I was driving back from Twin Falls Idaho on Tupper Grade heading West I saw three very bright stars just above the hills forming a curved line pointing to the right. About 2 minutes later I look back up and two of those stars are missing and then they reappeared but were floating in the air disappearing and reappearing. five minutes from when I first noticed them I arrived at home and looked back at them and then two disappeared and seconds later I heard two very loud booms and a gust of wind on a non windy day. The third one that never changed in any way disappeared five minutes after the others.
