I was looking at the sky while having my last cigarette for the night, and noticed a very bright light appear in the northern sky. i thought at first it may be an airplane but it only had the one bright white light. i thought, search helicopter. then, it split in to 4 in a diamond pattern. i said "huh". then it was 6. as i continued to watch it was suddenly 8 of them and all smaller than the original. they flew in odd formations, hovered several times, split off and 4 went out of sight toward what seemed like the air force academy. this was the first of 3 separate, but similar incidents. there were 2 other witnesses from the last time, but of course they laughed at me saying they were ufos, and i have no way to contact them if they did care. i was unaware of the existence of mufon until recently, or i would have reported it then. they happened just about a month apart, the last one around may 2017. i have no photos nor videos, i am sorry to say. they looked to be saucer shaped but they weren't close enough to be sure of the shape or sizes. all 3 rimes it started as one big light, then split to smaller, they spread out, then regrouped in to the big one and disappeared as instantly as it appeared. i am open to speaking with someone further, if you have any more questions.
