71-508 2025-10-18 01:50 ToO Principia, GSC_04315-01020, HD1368,
HD19445, Kamo, HD283886, GJ246, Roberta,
HD243687
ALIj180066 - ALIj180071, ALIj180073 - ALIj180087, ALIj180114 - ALIj180155 Problems with acquisition of local analogs HD243687 and GSC_04315_01020. Otherwise all targets observed successfully through thin clouds and approx. 0.7 arcsec. seeing. For GSC_04315_01020, the coordinates in the OB pointed the telescope to a completely different field than indicated in the finding chart. In the field given by the OB coordinates there were no bright stars. I pointed the telescope manually to the coordinates written on the finding chart's coordinate system - the target and corresponding field was visible at these coordinates. Please check that this is the target that you wanted. For HD243687, when pointing the telescope to the OB coordinates, the field of view did not resemble the finding chart, and the object was not visible. A similar object with a more correlated field was found approx. a minute RA/DEC away from the given coordinates. This object was observed. However, the correlation between the finding chart and the field is questionable. Please check that this is the target that you wanted. Observed

HD19445
ALIj190253 - ALIj190272 One science with 3 correlated std. stars observed - rest missed due to weather. Observed through clear skies and approx. 1 arcsec. seeing. Observed
71-508 2025-11-23 00:27 ToO HD1368, Principia, HD19445 ALIk230068 - ALIk230072, ALIk230079 - ALIk230083, ALIk230105 - ALIk230109 GSC_04315-01020 couldn't be observed due to cloudy weather. Observed

71-508 2025-12-16 00:52 ToO HD1368, HD19445, Kamo, Roberta,
HD243687, GJ246
ALIl160088 - ALIl160092, ALIl160199 - ALIl160203, ALIl160221 - ALIl160235, ALIl160251 - ALIl160255 Observed all targets with clear skies and seeing around 1.5" - 2". The observation for the solar and local analogs were identical for the two groups, so I only observed them once. Observed
71-508 2025-12-17 00:35 ToO HD84937, SA102-1081, Schalen, HD110747 ALIl170449 - ALIl170453, ALIl170481 - ALIl170497 Observed during high clouds and seeing <1.3". Schalen was a bit tricky to find, please check that the target is OK. Observed
71-508 2025-12-18 00:36 ToO HD84937, HD110747, SA102-1081, Schalen ALIl180233 - ALIl180237,ALIl180284 - ALIl180288,ALIl180289 - ALIl180293,ALIl180294 - ALIl180299 All targets observed during thin clouds and seeing varying from 0.7 to 2". Observed
71-508 2026-01-12 00:50 ToO HD1368, Principia, HD19445, HD26710,
GJ246
ALJa120069 - ALJa120073, ALJa120078 - ALJa120084, ALJa120085 - ALJa120089, ALJa120108 - ALJa120112, ALJa120113 - ALJa120117 Successful observations of HD1368, Principia and HD19445, but failed for GSC_04315-01020, resulting in an overall failed block 33_2653_1201. GSC_04315-01020 failed due to a mismatch in coordinates between the finding chart and target. Successful observations of HD26710 (observed twice by mistake) and GJ246, but it was not possible to observe Roberta* and HD76151 due to high levels of humidity after 23:15, resulting in an overall failed block 33_335_1201. Failed
71-508 2026-02-18 00:33 ToO HD26710, Kamo, GJ246, HD76151 ALJb180077 - ALJb180097 Target and standards observed in good conditions Observed
71-508 2026-02-19 01:04 ToO HD26710, Kamo, GJ246, HD76151, Schalen,
HD110747
ALJb190135 - ALJb190139, ALJb190147 - ALJb190155, ALJb190176 - ALJb190183, ALJb190184 - ALJb190190, ALJb190191 - ALJb190195, ALJb190196 - ALJb190200, ALJb190239 - ALJb190244, ALJb190246 - ALJb190250 Clear skies, and the seeing was oscillating between 0.7" and 2.1". For the target "Kamo": Observing conditions affected by thin cloud. Seeing unfortunately varied during the sequence between 1.8" and 2.1" arcsec. The target appeared off-centre on the slit, although a clear spectral trace is present in both 300 s science exposures. Flux levels are consistent between the two frames. Observed

HD110747
ALJb210072 - ALJb210076, ALJb210080 - ALJb210105, ALJb210331 - ALJb210340 Observed under (mostly) clear skies and good seeing. Observed
71-508 2026-03-12 00:43 ToO HD76151, GJ246, Schalen, HD110747 ALJc120149 - ALJc120158, ALJc120185 - ALJc120196 Target observed with clear skies and seeing 1.6 at the start of exposure. Please note that the finding chart for GJ246 is terribly out of date as the star, which I assumed was the wanted standard, has a high peculiar velocity. Consider using a more up-to-date finding chart in the future e.g., the acquisition image from today. Observed
