No problem to report. The best spectro focus was set for about 8.5 C. 23:45Z started ventilation. Night: ------ 00:56Z Sunset 02:10Z Enclosure off, topped-off spectro secondary dewars, checked top/bottom balance, did a test slew, checked fiducial crossings for each axis, mounted cart 07, and started the DIMM. 02:20Z Evening twilight 02:37Z Cart 07, plate 3264 (Jan09a_SEGUE2). An FK5 was used to find the field. The first guider frame was #988. Plate was declared DONE; problems notwithstanding.

When we tried to pull the enclosure, the 2.5_meter would not move because of the stop_button in the control room and also the TCC stop_button. Although the control_room stop_button was not pushed in, the MCP Interlocks Display indicated this E-stop button as in an activated state. Steph did an inspection of the stop button and then tighten its plastic cover, which fixed the problem. Jon Brinkmann bypassed the TCC stop_button at the interlocks panel of the lower enclosure, which allowed each axis of the scope to clear. We left this interlock bypassed. FYI, the TCC stop_button is a loop of wire on the back of the "2.5-meter Control Room E-Stop Fiber Relay" box in the computer room. Jon removed and reseated the wire, so the problem may be fixed now. But, we are not sure. Post Note: During our second exposure of the night, the scope halted is if a stop button had been pushed it. So, it would probably a good idea to check the e-stop in the control room as well as the TCC stop-wire in the computer room for problems.
