I was walking the dog and I had my satellite app open on my iPhone and had the Hubble Telescope selected. It was displayed on the phone as just coming over the horizon but still blocked by terrain and houses. I was facing due west. The sky was 100% clear with an almost full moon in the eastern part of sky. As I was waiting for the Hubble I was looking almost straight up, about an 80 degree angle from the horizon. I noticed faint movement of light; just a dot that was very dim. I checked the app and no satellites of any kind were shown for that area. The object moved from south to north in the western sky on what seemed like an orbital path. It passed above Venus but below Ursa Major. I used my high power green laser to point at it. The laser goes at least 20 miles. I lazed it for about a minute then stopped and watched. Ten seconds later the dim light got super bright and flashed twice stopped then speed off in a different direction (west and up) then blinked out. Initially I thought it was a secret satellite but the flashing back, changing direction and blinking out makes me think it was a ship. Nothing in an orbital plane and at orbital speed could do what the object did. Just thought you would like to know.
