I often step out of my house around 4-5 am to drink my coffee and see if it looks like it might rain. About a month ago, I noticed a shiney cross shaped object in the upper sky. It/they are small to the eye and are different sized/brightness. I think this is do to their altitude. Thought they rotate are the earth as the morning arrives, they are not in the exact same location from day to day. They are not visable after the sun comes up. As I've stated usually I see on but sometimes I see up to 5 in a sighting. I am curios as to what they are. Please put my mind to rest a tell me what I'm seeing.
