two weeks prior to this sighting i recorded video of a possible ufo after dark in the same general location at or just above the mountains in berlin new hampshire .this was at the very peak of the same mountain but during daylight.it stood out because it became brighter after several minutes and it was at the very top of this mountain which i believe no one could access on foot or by any atv..when i zoomed in with my camcorder it appeared to be a similar shape to the video i recoded at night square. this is the fourth or fifth time seeing something unusual in that location. i first became interested in ufos when in 1974 i had a 30 minute sighting in east bridgwater mass.when with two friends we saw a domed shaped ufo emitting sparks and hovering over some powerlines maybe a mile or two away. after we watched this for 15 minutes we headed slowly down the road towards it when we knew we were nearby we lost sight of it in the treetops. we exited the vehicle and stood in the street as it slowly went over our heads just above the trees.this ufo had no lights on at this time and made no sound at all and was as big as a house.
