The only way to stop it was to reset the PC, but after doing that I noticed that the dome azimuth drive was slipping quite a bit after I restarted using Run. I don't know if the two problems are related but I'll look at the dome drive problem first.

Now the observing program is progressing as it should, it looks like the dome tracking problem was the root of the other problem.

The dome isn't blocking the sun so maybe this is another ephemeris problem. I used Obs to exit gracefully.
