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.

Proposal	Date	Time	Type	Targets	Files	Comments	Status
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	00:00	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. Info from PI that data is useless, set to failed with 0 time spent. 9/3-2026 AAD.	Failed
72-017	2026-03-07	01:14	SoftToO	2026dgt, 2026evy	ALJc070071 - ALJc070076, ALJc070077 - ALJc070082	Clear skies, and the seeing was oscillating between 1.5" and 1.8". A manual ThAr calibexp was taken.	Observed

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