03/04/2021	Saida Caballero	FIT	Caballero, Zamora, Fowler	CCD	10	0	Standard star fields. Filter wheel got stuck during a sequence. Restarted ACE and it started working again. Guider was not responding at first, but disconnected and reconnected the cameras and it also started responding.
03/03/2021	Gary Henson	ETSU	none	Spectrograph	0	8	High winds followed by fog/humidity closed mountain all night.
03/02/2021	Todd Vaccaro	BSU	Nicolette Terracciano	ARC Camera	7	4	I noticed during the last hour or so that the dome AZ was off from tele pointing (30 dome, 330 tele), but field looked ok; it was at high Dec (+50); upon stowing scope dome read 159.7 and tele read 179. About 3 hrs shut for high winds, but lost an hr trying to find focus as well. The Aux Instruments window always says "Moving to..." Does it ever say it arrives? Headers in images registered that the filter was in place and the Instrument display on the far bottom left indicated the change was made.
02/28/2021	Amy Lovell	Agnes Scott		CCD	8	0.2	Lightcurves and imaging for lab students. Tracking in West streaked even some 30s images. As reported by others, focus wandered around over the course of the night - final value 370000.
02/27/2021	Gary Henson	ETSU	none	Spectrograph	8	0	Spectroscopy of Massive Stars
02/25/2021	Gary Henson	ETSU	None	Spectrograph	10.5	0	Spectroscopy of Massive Stars All worked well.
02/25/2021	Tomomi Otani	ERAU	Andy Baran	CCD	8	0	Photometry time series (sub dwarf B) As other people already reported, the focus was unstable. Once we obtain the “good” focus, even the small focus change (change the number by 5000) caused the big focus shift, and we could not obtain the previous good focus when we changed the focus back to the original value. After having this mistake three times, we learned that we should not even change the focus once we obtain a “good” focus (the star shape is round but elongated). It took ~2 hours for us to obtain the perfect focus. But everything else was working well.
02/23/2021	Saida Caballero	FIT	Kamp	CCD	10	0	Binary massive stars. Did not attempt to use the spectrograph because it hadn't been functioning the previous night. Otherwise, did not run into any problems.
02/22/2021	Saida Caballero	FIT	Kamp, Klare, Le, Zamora	CCD & Spectrograph	2	8	Was not able to access the spectrograph arm on the telescope computer so did not observe with spectrograph. Had trouble focusing CCD and clouds were forecast to move in so closed for the night.
02/20/2021	Walter Van Hamme	FIU	Samec	FLI camera	6	6	Observations and analysis of Eclipsing Binary Systems, AH Gem and NSVS506667. Software stalled.
02/19/2021	Walter Van Hamme	FIU	Samec	FLI Camera	11 hours	1	Observations of Eclipsing Binaries AH Gem and NSVS506667.
02/21/2021	William Keel	University of Alabama	3 cats	ARC CCD	10	0.7	Galaxies in H-alpha, dead quasar survey. Focus 411000; major shift around midnight needing 45 minutes to get a new good value. Best guider focus -1000, in some directions the guider images always have substructure which compromised the quality of EW guiding.
