1-daylight sightings 2-quickly disapearingI have had two sightings since this first sighting. I remember the date of the first one because it was the night our city does fireworks and a few neighbors were out watching fireworks. I have had two more since then. These do not seem to be UFO sightings but, I cannot explain any of these things in any earthly way I know. I have heard you say on coast to coast you want all reports.. So here goes.The first appeared to be some sort of garbage bag floating in the air floating and spinning which seemed a bit odd but even stranger was behind it was what I can only describe as a "whiff" of black smoke floating along a bit oval shaped this "smoke" did not change shape and seemed to stay course in the sky. We waited for these things to come out from behind the trees and they never did. They seemed to just vanish.A few days ago I saw what appeared to be a very bright planet in an area of the sky that I know there are not planets. I walked to get a better view away from the trees and as I got to where I should have been able to see it better it was gone. I didn't see it travel anywhere and I didn't see it disappear. It was simply gone.The third was what appeared to be a flock of birds.. but, they seemed to be changing colors from black to white- they almost appeared to be changing color as somehow light was reflecting from different angels. I'm not sure how this is possible outside. It looked like two flocks of birds not really flying anywhere but being stationary they both appeared as the opposite’s colors one "flock" being black the other white as they were changing colors they were the opposite colors of each other.. IE~ while one was black the other was white, as I looked down to cross the street and looked back up again just mere seconds the whole thing was gone.. What struck me odd about these three things was the quickness of what I was seeing to disappear and the fact that two were in daylight.I have checked the box to be contacted by an investigator. I would like an explanation of these things if someone has time a short email is fine.
