I was walking into my home from visiting my neighbor, as i was opening the door to my house i looked up, noticing the big heavy dark clouds rolling in. what caught my attention was that the afternoon sun was lighting up the thinner edges of the clouds, it was a pretty contrast of dark and light. that was when something caught my eye moving through the blue patch of sky along the edge of a cloud. my first thought was a seagull as the object was bright white and above the cloud layer(as white as the bright white, lit up edge of the clouds near it). but as it passed through the blue patches of sky, i could make out that it was a circle, a bright white, hazy circle. i say hazy because it seemed to be like the cloud, kinda transparent (not that i could see through it though.) with a slightly darker spot in the center. ( i didn't have time to focus in on the center before it left my line of vision. my next thought was, "am i seeing a satilite, in the blue sky of the day? but it was just above the clouds, and they were heavy with rain." my mind struggled to solve what i saw... it took a minute to digest it and it happened pretty fast. about 3.5 seconds. there was no sound at all from the object, it moved in a straight line which brought it above the cloud layer where visual was lost.
