Object with two lights moving erratically after green fireball dissipated.This report is not about the green fireball I saw but what I saw afterward.2/6/17 I was walking my dog and something made me look up. I saw a large green fireball which then disappeared. I think I heard a very slight sound, sort of a crackling which may be why I looked up. The sound made me think it was a flare, but I know that was not a flare. Also, I believe I saw some red dots over to one side of the fireball.When the fireball was gone I continued to watch the sky because I didn’t know what may happen next. Then I saw two tiny dots traveling together like headlights. But these were so far away there was no glare to them. It was moving in the same little cloud area that the fireball was in. This vehicle (?) was moving up, down, sideways, left & right and finally down on a right angle then it got covered by the little cloud. I stood and watched to see if it would come from behind the cloud and eventually it did but got covered again.Anyone seeing this would agree that this vehicle was searching for something. It moved at a slow pace and in erratic directions.FYI it was a cool clear evening, although there were white clouds here & there visibility of the stars and cloudless part of the sky were beautifully clear.
