I saw what looked like a twinkling star with lights on it that were green, red and white - flashing.I/we were out on our deck enjoying the evening (6 of us) and I saw a star that was brighter than the others and twinkled enough to get my attention. When it twinkled, I saw diferent colors. Red, green and white - flashing. We got out the binnoculars and saw more clearly the individual flashing lights. It was stationary for a long time. Then after 11:00 sometime, I saw the it was gone. It had been located in the North just above the tree tops in a distance. Then I looked to the east over Lake Erie (NE)and there it was. We went to bed at about Midnight so I do not know what happened to it.I had seen this star(?) a week or two before in the northern sky but this time, I asked my friends to view it also. We all agreed it was quite unusual. In all, 7 of us saw it. Two teachers, one scientist, one government employee, two marina owners and one teenager. Only four of us saw it in the eastern sky - the others had gone in by then.I would appreciate it if you could let me know what you believe it was. Thankyou. I plan to look for it again when we go down there this weekend.((NUFORC Note: We suspect a twinkling star may, indeed, have been the cause of the sighting, but that is surmise. PD))
