Hello list, If NROL-20 (USA 186, #28888, 2005-042A) or its rocket was in the second elset below, it would have been briefly visible from my location at 19:38 UT. I used my digital camera to monitor the general area (50x33 deg) from 19:29 to 19:59 UT with 1 minute exposures. Though some clouds passed during this time, the images show no satellite trails. From images I took of Lacrosse 5, I estimate that I would have seen anything brighter than mag 3.
