Noticed it at about 9:34/5, texted my friend at 9:36. clouds to the west (over the city, and mixed in with the moon), to the east, sky was crystal clear. i was admiring a dipper (the big? i don't know), when i saw the ufo first from the northeast heading south. at first, fast but not erratic (yet), it began to disappear for a second or two at a time, then reappear a little ways away (still on course). it then began to ping pong dart around the sky, while still randomly disappearing and reappearing. it seemed to last for a minute or more. i eventually lost sight of it as it traveled southeast, and clouds began to move over then from the west.
