We were camping for the second time at this location. my husband was taking pictures at night of the stars. we were located at the following coordinates, plus or minus a 6 feet radius. since it was dark with no surrounding light, he set his camera to a setting of f/1.7 with an exposure time of 15 seconds. we never saw those lights live, we just saw them afterwards when my husband worked on the pictures on the computer. clearly, those lights were not stars nor airplanes, because their shifting paths and their trails are something we never saw before.
