68-501 2024-10-01 02:23 SoftToO SP1550+330, ZTF24abgjdxk, ZTF24abiesnr ALHj010170 - ALHj010185, ALHj010305 - ALHj010314 All targets were observed successfully, although ZTF24abiesnr had to be retried as seeing was so bad in the first attempt. Observed
68-501 2024-10-04 01:57 SoftToO SP1550+330, ZTF24aaleeji, ZTF24abdiwwv ALHj040079 - ALHj040085,ALHj040109 - ALHj040116,ALHj040161 - ALHj040168 There was only time enough in the schedule to observe two of the science targets. Observed
68-501 2024-10-05 02:44 SoftToO SP1550+330, ZTF24aawrofs, ZTF24aaysowl,
ZTF24abjjpbo
ALHj050053 - ALHj050059, ALHj050071 - ALHj050079, ALHj050091 - ALHj050108 Observed in clear skies with seeing below 1.0" Observed
68-501 2024-10-18 01:13 SoftToO SP1550+330, AT2024wpp, ZTF24ablxiwv ALHj180101 - ALHj180107; ALHj180175 - ALHj180182; ALHj180188 - ALHj180195 Targets were observed with clear skies and variable seeing. The OB for ztf24abjjpbo was not done and instead we observed the same target for P70-014 and shared the time. Observed
68-501 2024-10-19 01:52 SoftToO SP1550+330, BD174708, ZTF24aaysowl,
ZTF24abjjpbo
ALHj190058 - ALHj190064 ; ALHj190076 - ALHj190080 ; ALHj190089 - ALHj190105 Observed the standard at the beginning of the night with bad seeing and therefore with the 1.3 arcsec slit. However we also observed BD174708 with the 1 arcsecond slit for a different proposal, and the observations of this standard was shared so it can be used for the flux calibration. The two targets were observed through thin clouds and seeing of around 1 arcsecond. Observed
68-501 2024-10-27 00:00 SoftToO No observations could be taken due to bad weather. Failed
68-501 2024-10-31 00:57 SoftToO ZTF24abdiwwv ALHj310159 - ALHj310166 Seeing was a bit worse at 26 degree elevation than I thought, ~1.4''. On the other hand, as the target is rising, this setup was most likely the correct decision to use. Thin clouds appeared in the sky during the observation. Strong H-alpha line in Quickspec. The standard star was not observed, because another standard star with the same setup (Grism 4 and 1.0'' slit) was obtained. These calibration files are ALHj310148 & ALHj310149. Observed
68-501 2024-11-05 01:41 SoftToO ZTF24abdiwwv, ZTF24abiesnr, SP1045+378,
SN2024ehs
ALHk050234 - ALHk050244, ALHk050293 - ALHk050308 The seeing got worse throughout the night. All targets except ZTF24abgjdxk were observed. The target was missed due to a hard ToO that had to be observed at the start of the night. Observed
68-501 2024-11-07 00:29 SoftToO SN2023iop ALHk070012 - ALHk070016 Target was unsuccessfully observed in the first attempt due to low visibility. A second attempt was made with thin clouds with visibility approximately 1.3", with a successful observation. Observed
68-501 2024-11-09 01:11 SoftToO ZTF24abiesnr ALHk090135 - ALHk090148 Observed through thin clouds and seeing around 0.8-1.2 arcseconds. Observed
68-501 2024-11-18 00:00 SoftToO No observations could be done due to bad weather Failed
68-501 2024-11-19 00:00 SoftToO Targets could not be observed due to high humidity Note that the requested standard star cannot be observed at this time of the year (I noticed it yesterday as well but forgot to note it down) Failed
68-501 2024-11-24 01:31 SoftToO ZTF24abdiwwv ALHk240026 - ALHk240039 Seeing was between 1.3" and 1.6" throughout the observation. Please choose another standard star because the one included is not visible at this time of year. A standard star will be observed as part of another proposal and the data is accessible in the calibs folder. Observed
68-501 2024-11-27 00:00 SoftToO Target could not be observed due to high seeing Failed
68-501 2024-11-28 00:00 SoftToO Could not observe target due to bad weather conditions Failed
68-501 2024-12-02 00:33 ToO HD19445, ZTF24abdiwwv ALHl020122 - ALHl020126; ALHl020132 - ALHl020137 Standard star data was shared with other proposals. Second target was observed according to the requirements. Observed
68-501 2024-12-07 01:15 SoftToO ZTF24abdiwwv, SP1045+378, ZTF24aapvieu ALHl070219 - ALHl070220,ALHl070344 - ALHl070350,ALHl070373 - ALHl070380 Observed with clear skies and sub-arcsecond seeing. Observed
68-501 2024-12-19 01:02 SoftToO SP2209+178, ZTF24aaysowl, ALHl190106 - ALHl190112, ALHl190128 - ALHl190136 Clear skies. Seeing conditions varied a lot, so unfortunately the SP2209+178 standard was done with the 1.0'' slit at 1.2'' seeing, while ZTF24aaysowl was observed using the 1.3'' slit at 1.6'' seeing. Observed
68-501 2024-12-20 00:39 SoftToO ZTF24abdiwwv ALHl200079 - ALHl200083 Clear skies and sub-arcsec seeing Observed
68-501 2024-12-29 00:59 SoftToO ZTF24abdiwwv ALHl290132 - ALHl290146 Observed
68-501 2025-01-02 00:36 SoftToO ZTF24aaejecr ALIa020154 - ALIa020162 Seeing of around 0.9 arcsec and clear skies. Observed
68-501 2025-01-06 00:26 SoftToO ZTF24abyatjx ALIa060247 - ALIa060253 Good seeing Observed

68-501 2025-01-17 00:00 SoftToO SP1045+378 ALIa170230 - ALIa170236 Setting as failed because we were only able to observe the standard due to time and weather restrictions. Failed
