About 5 minutes after the beginning (9:35ish) of the annual 4th of July fireworks at Hampton Beach, NH., I witnessed a small glowing red orb. At first I believed it was a Chinese lantern, which I had seen many of earlier, but it was stationary. After a few seconds, the orb began to move against the breeze in a straight line (east to west) very slowly. The orb again stopped for a few seconds, then ascended in a straight line, went stationary again for a few seconds, descended, went stationary again, then traveled west to east on a straight line. The orb, at times, became partially obscured by a house but would either ascend above it, or move east of it to come into few. The object was never lower than 45 degrees off the horizon but probably ascended to about 75 degrees above the horizon. There were no visible flashing lights and no sound. Seabrook Nuclear Power Plant lies just about mile west of the beach and the object seemed to split the difference of the two while the fireworks were going off. The orb then descended behind a building and I never regained sight of it. I was very excited and frantic while trying to keep the orb in sight. About 15 minutes after the event, I started to think of other possibilities. The most probable being a drone taking video of the fireworks from an elevated position. My wife also saw the object move east to west after being stationary for about 30 seconds.
