Yellow/Orange/White sphere seen by 3 in Rochester NHLast evening, 10/12/2015, I went out to my truck to get a bag of groceries when I noticed a bright, flashing light. It was strobing, then it would stop and go very bright, then strobe again. It was a white/yellow/orange combination of light. It was just sitting there in the North East just above the tree line. I ran into our house and got my wife, she came out to the front of our home, watched it with me for about 30 seconds, then it moved to the North.We could no longer see it from the front of our house so we went out to our back deck and was able to see it just over the trees. It was very, very bright, moving funny. A little to the left, then up, then back. After about 2 to 3 minutes, right before our eyes, it vanished! At this time our daughter came over and wanted to know what we were doing, we told her what we saw. After about 5 minutes of scanning the sky, BAM, it repapered right where it had vanished. It seemed much brighter, moving a bit erratic and strobing faster. After about 2 to 3 minutes, it moved up and to the north, then in a second vanished again. We watched for another 10 to 15 minutes but it never came back.What we did notice is that after about 20 minutes after in vanished for the last time, there were a number of airplanes!! We did not see one in the sky while we were watching the “UFO”, but after we counted at least 8 in the sky over and around where we saw the light. Our son is very much into UFO’s and told us that when something like this happens and you see a number of planes, something defiantly is going on. We are going to continue to monitor the sky every night for a while to see if it comes back.
