* Were the clocks synced? Make sure the [SYNC CLOCKS] button on Cosmic Debris has been pushed to start the night. If the OPLE server does not display the correct CHARA time and the errors don't read (0) or (1), the clocks were not synced. As the VME runs on its own clock and does not use the NTP server, it can drift over the course of the night and cause problems with finding fringes, even if it was synced at the start of the night. Syncing the clocks multiple time during the night may help to avoid this hidden clock problem. | * Were the clocks synced?

The star will be tracing an ellipse, figure eight or other looping shape. This means the tracking gain is too low. You can damp this out with the telescope or dome gui by disabling the scope, then re-enabling it. Adjust the gain upward and watch it on the next slew. \\ \\ In all cases if either gain is too high the scope will go into "Fog Horn" mode, which is bad. You always want to use the lowest gain that still allows the scope to work as best as possible. If the tiptilt tells you the scope is oscillating slowly, the gain may be too low.
