Sky Cam takes one photo every second. The timeframe was 5:48pm - 10:48pm
The first few frames you will notice in the lower right hand quadrant a moving light going from right to left that makes an abrupt 90 degree turn.
Besides being a quite active night you will also notice that around 7:40pm there are 4 very fast moving objects that come into frame. My best guess is the F-4's were late getting back to Fallon NAS. But then again who knows what's flying up in our skies at any given time.
