4 objects appeared in the eastern sky approx 30 degrees above the horizon near jupiters position at the time.they were very bright as they outshined jupiter which was at magnitude -2.9 . they flew in a formation of 4 for a time (lazily).2 broke off to the north while the others bobbed up & down & twowards each other.they never seemed to get closer and there was no sound. what stuck me as odd when i first saw them as they were perfect triangles of light .not lit on each point, but solid light.when i first saw them they were bluish white,but when i came back out with my neighbors they seemed more reddish.the only reason i was looking in that area was i was trying to find jupiters rising position.the sky was not wide open at that position so i dont know how they left (blocked by trees and houses ).they couldnt have been helicopters because at the appearent size they were at ,you would have heard them. they were @ about twice jupiters appearent size in the sky.bu! t i got the feeling they were quite distant.the triangles were well defined,sharply outlined light with no fuzzines at the edges.i have been observing the night sky for some time and have never seen anything like it.i was so fascinated by them but i had to leave them for a few minutes (2 or 3 tops) to get my neighbors so they wouldnt think i was lying or a fruitcake.
