Source:

Flashing light moving very very slowly across the night sky moving from west-80 deg. high moving south east it covered about 10 deg. in 15 min. at one time it looked like it could be some kind of drone very high in the sky because it looked like it changed direction slightly. im not positive about that. over time it seemed to be going in one direction. it flashed sometimes very bright and sometimes not so bright and as it got higher in the sky it got dimmer as it got to 90 deg. the flashes were about 20 seconds apart.
