Software/Control PC Issues
There seems to be a light on in the dome. I do not know where to switch it off. The image -D-drive on the camera PC is full. I did not receive a warning it just wrote empty files to disk. They of course displayed normally in DS9 and it took me a while to notice the problem. I was able to clear some old files from a colleague.

Equipment Failure
Asteroid. When I first logged on, the CCD camera would not respond to commands-- actually, it would appear that it was working, but not actually take any images. After four restarts of the CCD computer it begin operating correctly. I restarted the telescope computer along-side the CCD computer and when it came back up, many of the control windows were blank. Several restarts later, the controls were all back and everything except one thing appeared to function-- that one thing was the telescope pointing. The telescope would accept commands to slew to a particular area, but would not actually slew to the new location-- it stayed where it was, with "slewing" never disappearing from the control window. The hand paddle would not move the telescope either. Several more restarts had no effect so I closed up.

Connection Issues
Was observing from home; my Internet connection failed just before sunset at CTIO. Relocated to the university and resumed observing. All worked fine until about 12:30 am EDT. While slewing to a target the N and W limits turned red, even though the telescope was east of the meridian. I was able to close the mirror covers and the dome, but could not budge the telescope. Restarting ACE and the telescope computer did not help. I've informed Peter Mack and Brian Blondell of the problem.

We completed the procedure to reset the DIO96 board (Shutting down the Tele. computer and power-cycling the tele computer and ACE control cabinet.) The camera was still not connecting. We then tried to power cycle the camera and the camera computer. using the APC switch rack. The camera computer did not come up again. We were unable to connect to it.

White dwarf time series photometry. T=15C, focus=129500 at start of night with sudden change of -1500 in late morning. Seeing was mediocre at start of night (2" across mountain) but improved to 1" after local midnight. Used guider, with generally very good results. Target was at Dec=-10; at HA=-1:30 the telescope moved south by about 1 arcmin over 5 minutes - this motion was too fast for the guider to compensate, and the ACE RA/Dec readout did not register any change in position. At RA=+2h, the reverse happened - telescope moved north by about 1' over 5 minutes without the positional readout changing - lost about 15 minutes each time futzing about, resetting guiding, etc.

Lost about 1 hour fiddling with focus and filters trying to see if the seeing was instrumental (it wasn't).

Taught an evening lab, so lost the first half of the night. The guider stopped working properly about an hour in. The guide star was in the middle of the field, but showed very large x and y corrections, so would wander to the edge of the guide box and bounce around there. Not sure what was wrong. I didn't hit Calibrate, but that seems like it may be the most likely cause.

There was a jump in best focus values during the night. I could not tell if the best focus actually changed significantly in a short time (unlikely since the temperature changed slowly and steadily), if the focus encoder value changed, or some other issue.

AGN monitoring program. Everything worked fine for about an hour, long enough to get bias, flat, and dark images. When slewing to my first target, the telescope stopped, and the TOS indicated that it had reached the S and W limits. It was actually pointed northeast of the zenith. Peter was able to get the telescope moving again, but by then clouds had rolled in and the humidity climbed to over 80%. I gave up after midnight EDT. Previous observers reported similar limit issues in August. Observers should note that the problem may recur.

Observed active galaxies. The telescope systematically pointed about three to four arcminutes north of target. About 30-60 minutes east of the meridian (depending upon the declination) the telescope appeared to oscillate in declination, resulting in images severely elongated in the north-south direction. The connection to the CTIO computers was terminated on three occasions during the night as noted by earlier observers), but reconnecting posed no problem.

Can't see sky at CTIO because they are possibly disconnected? Two slews needed another "Go" or time to finish. One radmin drop of Sara Telescope. Last observations at altitude 53 to east resulted in trails first tilted right then left, then straighter (N was down, EW horizontal) Pointing good. Maxim timed out and was not used. Seeing about 1"and weather great.

Equipment Failure
Observing program: backup program (griz time series of V445 Oph and V Ind), due to thin clouds making the original program unfeasible (absolute photometry of Cepheid comparison stars in the Sloan bands). There were technical problems on two occasions, first when observing V445 Oph around azimuth ~ 0, the camera FoV would produce very strange vertical (DEC direction) PSFs while exposing. Sometimes the length of these reached over 300 pixels! This lasted for about an hour, ending around UT03. Secondly, while observing V Ind, around UT06:50 the telescope got completely stuck. I couldn't move it with giving it movement orders, offsets, or the paddle. The only thing I could do is to close the mirror cover and the dome, to leave the telescope in a safe state. As this happened near the end of the night, we didn't lose too much time, but I couldn't attempt doing sky flats.

Photometry time series to check pulsations. The telescope suddenly started moving to the DEC direction (the target's y position moved 2 pixels/image). So I moved the telescope to the zenith and moved it back to the target, then the issue was solved. The camera connection suddenly disappeared while taking images, so I used the regular procedure to reconnect the camera. The header's observation time did not have decimal digit (so we could not obtain less than 1 second accuracy).
