P70-018: Unraveling the nature of fast blue optical transients

PI: Hanindyo Kuncarayakti

ALFOSC + NOTCam ToO program with override status

ToO triggers have override status.

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/70-018/.

For the observer:

Go to the directory
cd ~/scripts/70-018
List the available scripts
ls -lrt
and execute the OB generated scripts requested.
If you cannot find the corresponding observing script, please (re-)compile it from the Queue interface.

In the case of NOTCam, make sure that differential skyflats are obtained for the camera and filter setup that is requested.

Remember to fill the ToO or SoftToO tracking log of this program.

Proposal	Date	Time	Type	Targets	Files	Comments	Status
70-018	2024-10-01	00:28	SoftToO	AT2024wpp	ALHj010247 - ALHj010267	The target was observed successfully. The data was shared with proposal 70-014, so the time spent is cut in half. The files for the spectroscopic standard for grism 4 (HD19445) can be found in the calibs-folder. Feige110 was not observed because this standard used the same setup.	Observed
70-018	2024-10-04	00:45	SoftToO	SP1550+330, AT2024wpp	ALHj040079 - ALHj040085, ALHj040140 - ALHj040160	Shared from 70-014. Two B-band polarimetry files might not have been shared correctly in the software. If this is the case, please contact us or the PIs of 70-014 for assistance.	Observed
70-018	2024-10-07	00:39	SoftToO	AT2024wpp	ALHj070283 - ALHj070295	Observed in clear skies with seeing around 1.0"	Observed
70-018	2024-10-16	01:13	SoftToO	2024wpp	NCHj160187 - NCHj160240	Observed with clear skies, sub-arcsec seeing.	Observed
70-018	2024-10-18	00:22	SoftToO	AT2024wpp	ALHj180175 - ALHj180182	OB shared with P70-018 because of the request in the comments of P70-014.	Observed
70-018	2025-01-12	01:47	SoftToO	WFST241224a, WFST241214a, HD19445	ALIa120053 - ALIa120057, ALIa120067 - ALIa120071, ALIa120093 - ALIa120097	Clear skies, both science targets were observed with a seeing around 1 arcsec, and the standard was observed with a seeing around 1.2 arcsec	Observed
70-018	2025-01-29	00:00	SoftToO	HD19445	ALIa290114 - ALIa290117	Could not observe due to high wind. Only collected standard star spectrum at the start of the night.	Failed
70-018	2025-01-30	00:20	SoftToO	WFST250129a, HD19445	ALIa300052 - ALIa300060	Very high winds coming from the SE quadrant, so had to wait until the targets were outside the direction of the wind. However, due to the varying wind direction, they often fell within 85 degrees of where the wind was coming from and the script had to be aborted. Only managed to observe one of the targets and a standard star at similar airmass. Otherwise observed in clear skies and with relatively good seeing.	Observed
70-018	2025-02-27	01:10	ToO	WFST0523meth	ALIb270117 - ALIb270121	Observed with clear skies and seeing around 1.3''. Unfortunately, part of the exposure was vignetted as the lower hatch was closed due to high winds. On a first glance it seems the spectrum is fine, but let us know if this should have been set as failed. Standard star could not be observed due to telescope being closed because of high humidity	Observed
70-018	2025-03-12	00:00	SoftToO	SN2025bco, SN2025bpq	ALIc120144 - ALIc120153	Observed with clear skies but seeing above 2". Marked both as failed for this reason, but please let us know if the data is still useful.	Failed
70-018	2025-03-17	02:00	SoftToO	SN2024gvz, SN2024xeb, Feige34	ALIc170165 - ALIc170169, ALIc170239 - ALIc170248	Targets observed according to the requirements, with clear skies and good seeing for the most part. sn2024xeb target was visible in the acquisition image, and so was observed. The standard was shared with proposal 70-503 as they requested the same standard with the same setup and exposure time. The standard was taken at approximately the same airmasses for both the 70-503 and 70-018 targets.	Observed
70-018	2025-03-22	00:15	SoftToO	SN2025bco	ALIc220119 - ALIc220123	Aborted sn2025bpq due to time constraints. Observed bco with clear skies and good seeing.	Observed
70-018	2025-03-25	01:14	SoftToO	WFST0521jnjd, SN2025bpq	ALIc250252 - ALIc250258, ALIc250353 - ALIc250357	Two softToOs observed. One with clear skies. Seeing ~0.9'' at the start of the observation. The other was observed during astronomical twilight with the last few minutes during nautical twilight. Another proposal had identical standard star OBs, please use them.	Observed
70-018	2025-03-26	00:35	SoftToO	WFST0524aarnv	ALIc260144 - ALIc260148	thin clouds OK seeing	Observed
70-018	2025-03-27	00:34	ToO	WFST0525ksxh	ALIc270116 - ALIc270120	Clear sky, bad finding chart	Observed
