We too see extremely bright flashes of pin point light in the NE appx 50 degrees Altitude, night sky, similar to a camera flash bulb from a great distance off, it doesn't light up the sky, or the general area, it is intensely bright from it's singular location. It might reappear again in a new nearby location. We know the stars and satellites, we know a meteor when it shoots across the night sky - These brilliantly bright flashes of light are different and are nearly always in the same area. The flashes of light would visually be compared to the size of Jupiter or slightly bigger from our perspective but MUCH brighter.
At first we thought that it was an iridium flare, but since it didn't behave like one we wrote that idea off. Then we thought it might be a tumbling satellite, but the question remained, how many satellites tumble and flash in the same location every night.
If we stay out long enough, we too see them almost every night. When there is a full or bright moon it is more difficult to see them.
