68-803 2023-10-01 00:00 SoftToO Scheduled service observations are not logged here. Observed
68-803 2023-10-16 00:59 ToO HD14069, BDp64106, K07S06Q ALGj160170 - ALGj160185, ALGj160196 - ALGj160211, ALGj160226 - ALGj160241 Observed during no/thin clouds. We aborted the first observation of 2007 SQ6 because we would not have been able to rotate the building long enough to the initial direction. The second observation was successful, except that the quality of 202.5-degree and 292.5-degree exposures was damaged due to lags in repositioning between the exposures. Observed
68-803 2023-11-10 00:44 ToO K19C04E, BDp25727, HD64299 ALGk100337 - ALGk100368, ALGk100372 - ALGk100387 All targets observed during a clear sky. K19C04E was able to be observe without repositioning, although the observing instructions for fast targets were used. Observed
68-803 2024-01-08 01:04 ToO HD251204, HD94851, 613986 ALHa080155 - ALHa080170, ALHa080224 - ALHa080239, ALHa080242 - ALHa080257 Observed with clear sky and seeing around 1-1.5 arcsec. Observed
68-803 2024-01-24 00:00 ToO 85182 ALHa240161 - ALHa240170 The ToO (85182) observations failed due to bad weather. The standard stars were missed completely and two quartets of noisy frames were obtained. Failed
68-803 2024-01-27 01:47 ToO 85182, HD251204, HD94851, 483508 ALHa270112 - 143, ALHa270189 - ALHa270233 All targets observed, but especially with 483508 there was interruptions due to clouds. Seeing was around 1-2 arcsec. Observed
68-803 2024-02-01 00:37 ToO 483508 ALHb010344 - ALHb010373 Observed in clear skies with seeing around 0.8" When repositioning the guide probe at the start of the 225 deg observation, the autoguider failed, guiding was fixed upon a retry but this was unfortunately already halfway through the observation. The target was lost in subsequent exposures, so the OB was restarted. Observed
68-803 2024-02-02 00:48 ToO HD14069, BDp59389, 139622 ALHb020052 - ALHb020083, ALHb020247 - ALHb020262 Observed with thin clouds and subarcsec seeing. Observed
68-803 2024-02-15 00:51 ToO HD14069, BDp59389, 483508 ALHb150079 - ALHb150114, ALHb150122 - ALHb150137 Could not observe 85182 due to the close distance to the moon, observed 483508 instead. Targets were observed with mainly clear skies and some thin clouds, and seeing around 0.8 arcsec. Observed
68-803 2024-02-19 00:43 ToO 85182 ALHb190066 - ALHb190073 Tried to observe the target through some clouds, and with some vignetting from the lower hatch, which had to be kept closed (could not be observed earlier due to thick clouds). We lost the guide star when reaching angle 180deg., due to thick clouds covering the entire sky. Failed observations for the target 85182 and could not observe the standards, due to the thick clouds. Failed
68-803 2024-03-05 00:00 ToO ALHc050276 - ALHc050291, ALHc050483 -
ALHc050276 - ALHc050291, ALHc050483 - ALHc050498, ALHc050522 - ALHc050537, ALHc050540 - ALHc050549, ALHc050550 - ALHc050555, ALHc050556 - ALHc050560 Observed through thin clouds and with sub-arcsec seeing. Due to technical problems, the useful dome flats are ALHc050080-ALHc050127 and ALHc050141-ALHc050172. The OB 20240305_163693 was restarted a couple of times due to problems with the acquisition but was finally observed. The OBs regarding the Atira targets were also restarted a couple of times due to difficulty with the acquisition and guiding, due to the clouds, them being so low in the sky, and difficulty finding the target in the acquisition image for the spectra. This caused the standards Wolf1346, HD195034 to be observed into and past twilight. Please check Wolf1346 as the automatic finding chart was slightly confusing and seemed to point to an empty space right below a blue star, but I took the spectra of the blue star. Observed


The above information is collected from the ToO/Mon reports that have been created by the observer.
