P72-017: PRE-Supernova Targeted Observations (PRESTO) during the Rubin Era

PI: Maximilian Stritzinger


ALFOSC SoftToO

SoftToO triggers will be requested with ALFOSC in Nordic Service or technical time.

The OB generator will be used to request all observations.
The OBs will automatically appear in the OB queue and OB generated scripts will be automatically placed in the directory ~/scripts/72-017/.

For the observer:

Go to the directory
  cd ~/scripts/72-017
List the available scripts
  ls -lrt
and execute the OB generated scripts requested.

Remember to fill the SoftToO tracking log of this program.

72-017 2025-12-01 01:03 SoftToO ZTF21abwzocu ALIl010656 - ALIl010665 Observed this because it was the only target downwind, though it was observed outside LST limits and partly into the lower hatch. I will mark this as failed, but let us know if this should be changed to completed. Failed
72-017 2025-12-16 01:09 SoftToO sn2025afwg, 2025abov, 2024xdq ALIl160133 - ALIl160139, ALIl160180 - ALIl160184, ALIl160209 - ALIl160220 Observed with clear skies and seeing around 1.5" - 1.7". Observed
72-017 2025-12-17 00:45 SoftToO sn2025uvo,2025ztn ALIl170175 - ALIl170191 Observed during high clouds, varying seeing and wind conditions. There was an error after the HeNe arc, so I had to run the script again and continue from where the error occurred. Observed
72-017 2025-12-18 00:34 SoftToO sn2025uvo ALIl180123 - ALIl180127, ALIl180129 - ALIl180135 Observed during thin clouds and seeing <1".When doing calibration frames, got an error in XPA communication to ALFOSC and had to ctrl+c the script and restart the obssys. Ran the script again (reading out the science frame) just to do the missing calibration frames. Observed
72-017 2025-12-25 00:34 SoftToO SP2209+178, sn2025uvo ALIl250098 - ALIl250102, ALIl250132 - ALIl250138 Clear skies, and the seeing was around 1.2". Observed
72-017 2025-12-31 00:27 SoftToO sn2025uvo ALIl310071 - ALIl310078 Slit_1 attempts failed due to weather. Slit_1.3 successful. The requested std. star was missed due to weather, but another star for same setup was observed during the night. Observed
72-017 2026-01-10 00:35 SoftToO sn2025uvo, SP2209+178 ALJa100061 - ALJa100067, ALJa100068 - ALJa100074 Observed with clear sky and seeing around 1.1'' Observed
72-017 2026-01-18 00:00 SoftToO None None Failed due to high winds. Failed
72-017 2026-01-20 00:14 SoftToO sn2025uvo ALJa200072 - ALJa200077 First attempted as data quality looked poor so waited for darker time and moon setting. Observed through thin clouds and approx. 1.3 arcsec. seeing. Observed
72-017 2026-01-24 00:41 SoftToO SP1045+378, 2025qof ALJa240109 - ALJa240115, ALJa240124 - ALJa240129 Observed under clear skies and fluctuating seeing, however, science target had dimm seeing of around 1" throughout the observation. Observed
72-017 2026-01-28 00:39 SoftToO sn2025uvo ALJa280061 - ALJa280068 Observed with clear skies and good seeing. Observed
72-017 2026-02-20 01:03 SoftToO 2026dgt, 2026dmk ALJb200190 - ALJb200195, ALJb200238 - ALJb200243 Clear skies, and the seeing was oscillating between 1.0" and 1.5". Observed
72-017 2026-02-22 00:38 SoftToO 2026drr ALJb220220 - ALJb220225 Observed under clear sky and seeing around 1". Observed
72-017 2026-02-24 01:26 SoftToO 2026efq, 2026dyr ALJb240123 - ALJb240128, ALJb240142 - ALJb240147 Targets observed with clear sky and seeing around 1.5'' Observed
72-017 2026-02-28 00:38 SoftToO 2026dgt ALJb280104 - ALJb280109 Observed with cloudy patches and seeing about 1.1-1.5''. Moderate winds contributed with some turbulence. At 1000s left of the exposure, a large cloud moved in front of the source. At 750s left, the cloud passed and the source was visible again. Observed

 

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