I was taking trash to dumpster when i noticed lights in the eastern sky that were blinking in an erratic manor. i watched these lights (3) as they moved in ways that i could not explain...They would accelerate so fast that it appeared to be a streak of light. i would try to track them...Only to see them reapppear behind where one would have expected them to have been. they would stop and hover...Then make another sudden acceleration. they would then move in patterns that one would expect out of a butterfly. several came close enough that i could identify them as being triangular in shape. over the space of about 45 minutes i observed lights further off in the distance that appeared to be lights rotating in a circle as a toy too would circle. i sighted them in the eastern sky and as i looked around saw them in all the cardinal directions. some appeared to be absorbed by others....Some seemed to.Be ejected by others (one light.Becoming two) i have never seen anything like this...It was amazing.
