red blinking light in sky over louisiana?

Here's the thing,We live in south-eastern louisiana. Thurs night at around nine p.m. my son and I noticed a red, white ,and blue blinking light in the sky. It was too high to be a cell phone tower and it was moving too sporadically to be a helicopter. I swear we weren't drinking but while we were watching it, it would disappear then return. it would move about in random movement (not straight up and down) sort of like it was flitting back and forth. Did anyone else see this? My husband seems to think this might have been a Satellite or something.
