Multiple flashing lights over a long periodThree of us were camping up in the Bigelow Preserve in Western Maine at Horn's pond campsite. At 7pm we decided to take the half mile hike up to North Horn to watch the sunset. After watching the sun go down i turned to look to the East for Mars. In the northeast a flash of light caught my eyes. It happenned several times an at first thought it may have been a firefly playing tricks with my eyes. Flashes got more frequent an we all began to see them. They appeared to be out in the distance 10-15 miles out against the shadows of the next ridgeline. The flashes were very bright alternating between blue/white and orange. The patterns were random. We at first were convinced they were explosions from military testing. We ruled that out knowing that the fire risk was to high for such activities. The lights most certainly were not planes or flares. The flashes varied slightly in intensity. The area we were watching was roughly in the area that the Appalachian Trail would be heading after it left the Bigelow Preserve, toward the Forks area of Maine. Among the flashes we could make out what appeared to be a red antenae like object that was not flashing but glowing. My two friends thought they also saw small objects in the sky being illuminated by the brighter flashes. After 15 minutes or so we were more than a little "freaked out" by what we were watching and decided to make the half mile descent back to camp. I know that this is pretty out there but it was a very clear night and all three of us watched for a good amount of time. I would love any info that anyone has abouth this phenomena. This whole experince has me considering another post about a daytime sighting that we had two weels earlier also in Western Maine. I'll get to that after I talk to the other observers. Thanks.
