At 05:27 6/23/2017 UTC (22:27 PDT Thursday night) we received a short timing GPS-EY error which cleared quickly. Looking at DAQ trends for this system, this appears to be another bogus GPS error. The attached dataviewer trend (second trend, 5 minutes duration, 20:25 - 20:30 PDT Thu 6/22) shows that the reported number of tracked satellites drops to zero, but the not-tracking-satellites flag does not report this. Also the number of visible satellites stays at 10 during the glitch.
