We are continuing the acceptance and development tests on the telescope begun in July, 2000. The work planned for our trip scheduled for 21-26 June, 2001, had to do mainly with further steps to make the telescope control system work automatically. This work went splendidly, although the weather was so bad we could observe on only one night out of the five. Lightning the first night knocked out the power line to the observatory for the first time in six years, requiring a new transformer, which the power company replaced the next day. Williamson integrated the startup code, weather checking, and star selection into the control program and ran a program to find and center a group of pointing stars under complete computer control. The telescope opened the roof, started up, found about 120 stars in two hours, shut down, and closed the roof without any intervention.

The work planned fell into four categories as follows:

1. MECHANICAL ADJUSTMENTS and augmentation of the telescope structure.
1. Adjust the limit switches in the secondary mirror cell and make sure the motions have sufficient range to focus and tilt the secondary mirror over the operating ranges expected. (Deferred to September.)
2. Set up the trial fiber to lead light from the instrument head into a video camera for tracking tests with a more sensitive camera. (Deferred to September.)
2. ELECTRICAL WIRING.
1. Use a laptop PC to reprogram the JPEG server to record more than one image and reset the program that copies images out of the device. (Deferred indefinitely.)
3. Work on the DRIVES and CONTROL SYSTEM.
1. Integrate automatic startup code into the control system and test it. (Williamson integrated code Eaton wrote to calculate the times for opening the observatory, starting to observe, and shutting down into the control system and tested the procedures successfully on one night.)
2. Put code for making log files into the telescope-control programs and test to see whether it degrades the performance of the control system. (We have thought some more about how to do this and started it by putting in log files to record the various pointings of the telescope.)
3. Integrate code to choose stars on basis of a calculated priority into the telescope-control front program to use in choosing stars for TPOINT. (Eaton and Keel have written a simulator with code for assigning ATIS-like priorities for observing stars, and Williamson integrated it into the control system and exercised it by observing a group of TPOINT stars. The distribution of stars in the sky was at least as good as expected from the simulations.)
4. Run more tracking tests with the fiber feed in the instrument head to determine the best exposure times and techniques to use for the guiding camera. (Deferred to September)
5. Run further acquisition tests with secondary mirror in place. (We did this on one night as explained in the introductory paragraph above.)
6. Integrate the roof-control commands into the control system and test operation of the roof under complete computer control. (Boyd finished the basic computer control of the roof in late May, and we have tested it from Nashville. Williamson added the procedures for opening and closing the roof into the control system and verified them.)
7. Get the telescope-control computers to fetch and use the weather data supplied by Fairborn Observatory through the roof-control computer. (Williamson added this check and tested it.)
