Five or six "stars" dancing/chasing each other in a circle.

At about 10:30 PM, Friday, July 1st, I walked out onto our balcony and immediately saw in the eastern sky five or six "stars" dancing/circling around each other.
My brother had followed me onto the balcony and heard me exclaim, "Holy s..., look at that!" I then reached for a pair of binoculars on the balcony table, and when I turned back to see them again they had disappeared. My brother said he saw them just before they disappeared and described them the same as what I saw.
The objects emitted no sound, and the sighting only lasted for about 3 seconds. They looked exactly like stars - the same size and brightness - but they were all moving around each other in a small section of the sky, in the area between the two actual stars of Altair and Tarazed.
Though I've read other people's reports detailing similar sightings, neither my brother nor I have ever seen anything like it. It was a shocking and incredible thing to see, and I wish I hadn't taken my eyes off it to grab the binoculars.
