Triangle-like lights seen flashing/blinking, moving circular then south west, then disappearing. Seen from highway 17C near Vestal, NY.Seen from car going south on 17C. Triangle like lights were noticed in sky near radio towers, glowing/blinking, moved in circle like pattern before moving considerably faster in a south west direction and disappearing. The whole event was witnessed from the car and only lasted a few seconds. I may be wrong, but I believe my cellular phone was acting strangely for a while afterward.
