AGN with emission-line clouds. Focus 97300, guider focus 800. Do not use the "save last image" button while another exposure is in progress - took me a half hour, two connector-client restarts and 2 dome azimuth resets to recover from that bit of genius. (I never did quite recover the setup on the CCD computer) Brian Brondel connected and tweaked the guider to remove E-W oscillations.

rOAp stars. The dome got stuck at 182 degrees. I homed it and then the dome tracked the telescope azimuth without another hitch. The telescope got "stuck" on the west limit at +3 hours HA. This was odd as I had slewed to the same hour angle just a few mins earlier. I checked the DIO96 bord and found that it was not operating. (The board was not present in the Instacal GUI.) I shut down the Telescope computer from software. Then powered off the Telescope control computer and the ACE control cabinet from the remote APC. A test of the DIO board showed "FAIL" and red lights on all its channels. I repeated the DIO board recycle procedure three times, occasionally recycling the power to the computer and ACE controls, instead of powering off and then on again. All attempts left the DIO board in the failed state.

White dwarf time series photometry. I followed Brian's safe dome handling instructions - dome opened fully despite saying "ajar" and closed fully. Dome camera not responding, so used target images to verify closure. Great weather, 0.9" seeing. Used guider; it worked well (focus 975). Toward end of run dome stopped rotating at an azimuth of ~255 degrees. Cycled azimuth power, homed dome, re-linked it, and all was well.

Eclipsing binary star. Controls for both the telescope and camera computers did not display when using Radmin. A reset of both computers was performed but still didn't display the controls. Did another reset for ACE (we thought maybe is was a connection issue, not a computer issue) and that displayed the controls. Once the controls were up, we couldn't open the dome. We tried following the dome door reset directions many times but the dome wouldn't open. Brian later logged on to help us. After his attempt, he informed us that the dome was stuck and could not be opened tonight for observing.

Seeing was marginal (2 arcsec or so); other ORM observatory DIMMs reported bad seeing too. Suggestion: Have wind speed in same units on Clarity, within the ACE interface (which I really liked tonight), and on the Closing limits on the SARA website.

The site map never showed NOT had dust warning, only GTC showed it. The mirror cover was showing as open when I logged on and not knowing if there's an issue there I left as is. I only took bias frames.

No tracking problems, but incomplete slew ("unable to complete slew...") message forced a full restart, and a re-setting my protocols. File space disappeared without warning, so all asteroid files and later darks were lost. Slewing was fine after restart.

At the beginning of the night telescope tracked for about 30 minutes without issue on a target while using autofocus and waiting for twilight to end.

The system worked well until we got to about 1hr and 20 mins west of the meridian. The scope was at an airmass of 1.12 and an altitude of ~62 deg. It was no where near any of the limits. Then, the scope suffered the first of five episodes of tracking failure and/or the "unable to slew due to equipment failure". In the first two instances, reselecting the target and slewing (the short distance) to it was sufficient to get it tracking again. Over the next three hours the tracking failed three more times with the "..due equipment failure" message. I notices that the not only was the RA tracking not working, but the the scope was also drifting in declination. These episodes were fixed by doing the full ACE restart procedure. Except that the filter wheel GUI on the camera computer also stopped working during the fourth episode. This resulted in a loss of filter and other info. in the file headers. During the fifth instance, the filter wheel GUI went away and could not be coaxed into starting up again. I tried two full restarts for this one. I was able to get bring the telescope control up again and park the scope. During two of episodes the camera GUI froze. It displayed the following error message. "tr1::bad_weak_ptr." Even after the full ACE restart procedure the old instance of the ACE control system was still present. It would crash and go away only when I clicked buttons on the service selector. The, a new instance of the camera control could be started.

Nearly complete waste of a beautiful night. Tracking turned off repeatedly. It took four complete restarts to finally get the telescope to keep tracking for more than 10 or 15 minutes. Observed for 2 hours and tracking turned off again, repeatedly. Three more complete restarts and I finally gave up. Tried several positions on the sky, with no success. Even when it was tracking it didn't track well. With the guiding on (which it didn't seem was very effective), the telescope drifted by several arc seconds every ten minutes or so. Also, the "Park" entry under "Presets" sends the telescope to the wrong position: it sends it to an RA of 0:00:00 NOT an HA of 0:00:00...and leaves the telescope tracking, which is obviously very bad. Oh, and the mirror covers never read closed, still read "closing."

I began the observation night very well without problems. In the middle of the night, it was necessary to do the full restart because the slew shows me an error (unable to complete the slew due to an equipment error), I did a full restart again and it was fixed. The big problem was at the end (close to 03:00 UT), it was necessary to do the full restart two times, and it was impossible to continue the observation. I finished because the tracking did not work.

Eclipsing binaries. Missed early flats due to telescope RA not reporting correctly to fits headers, which apparently is only occurring when tele is idle. Mirror cover was saying "closing" when I first logged on and continued to do so after I closed. I lost the majority of an eclipse egress due to tracking failures (over 5 times before I gave up on the target). It was failing ~+2 hrs HA at +78 deg. A full reset was needed to move the tele anywhere as it kept reporting an equipment error. After a full reset I could reacquire the target, but it would produce trailed stars after a few frames. When I went to another object that had yet to transit it started doing the same thing at HA 00:15:00. Something wrong on W side of mount?

Stopped tracking and attempted to restart it, but 'Slew Telescope' window showed an error (Unable to complete slew due to an equipment error). Restarted the system as usual (Full Restart). Problem persisted. -After restart 'Mirror Cover' window was stuck in 'Opening' for almost 5min. -Restarted once more. This time, no issue with mirror covers. Problem was only fixed for one single exposure (5min) and then returned. -Restarted a third time, and switched to a higher altitude source. Tracking worked afterwards.

At the start of the night when I opened the dome, it read as opening, but never got to "Opened." Restarting the software fixed this. The telescope tracking was not great. Five minute exposures showed drifting. There is no option to open the Guider GUI, so I couldn't guide. When I sent the telescope to Park position, it went to the correct place then started tracking. Had to hit Cancel to get it to stop tracking. And after closing the dome, it says "Doors ajar."

Dome azimuth was checked and improved with the Dome Azimuth restart. Ken Rumstay, Brian Murphy and Peter Mack all helped on various pieces of the problem. I was/am embarrassed that this was akin to forgetting to remove the camera lens cover. But the problem is tougher and will be looked at Monday. Good luck to all involved. (Dust was not a problem.)

roAp stars. At the start of the night, the camera and telescope computers were locked up, We power-cyc;led them. The telescope control was then not talking to the hardware. We carried out the procedure to restart the ACE node services and the camera and telescope controls then worked. Shortly after this, the dome stopped moving. We recycled the Azimuth control and homed the dome. The dome the worked perfectly until about an hour before the end of the night. The dome again needed to azimuth-cycled and homed. This was successful. I then allowed the scope to reach the western limit. It is currently stuck there. Could you move the scope off the limit? - Thanks!

Misunderstanding about availabilty of the night. CCD computer is very slow and has warning that disk space is low. Deleted all my files at end of the night. Autofocus failed multiple times. MaximDL has issues. I assume this is all due to the full disk space?
