Strange slow-moving red lights in the Northern sky at Exeter, NH at 22:00 hours on August 4, 2012.

We saw slow-moving red/orange lights going from right to left in an uneven formation in the Northern sky. They appeared to float, and there was no noise.  They went to one area in the sky, then appeared to turn and wink out.
Notified local authorities who said, "There is nothing to worry about."
Then called state authorities who listened to the description and number, and their comment was "Tthis is not NOTHING. More people should have seen this."  
This is the SECOND time we have witnessed this phenomenon, with about the same responses.  
What is going on??
