We have seen these fire ball orbs twice , both times in October. We live in a condo on the beach in Provincetown. Last time they looked like they may have co.e out of water or other side of sand castle motell . They went up one at a time made a hexagon shape then zipped off one at a time and disappeared at the same point kinda direction the sun sets here . This time we saw at least 4 over the town airplanes following but when airplanes got close they would blink then be somewhere else. This time made a formation of 4 in a row then zipped off. This time only me and my boyfriend saw them last October. Us my 21 year old daughter and 2 neighbors
