P68-020: Chasing the most exotic gamma-ray bursts

PI: Daniele B. Malesani

ALFOSC/StanCam+NOTCam ToO + SoftToO

ToO triggers have override status, SoftToOs can trigger in Nordic Service a nd Technical nights.

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/68-020/.

For the observer:

Go to the directory
cd ~/scripts/68-020
List the available scripts
ls -lrt
and execute the OB generated scripts requested.

Make sure that differential skyflats are obtained for the camera and filter setup that is requested.

Remember to fill the ToO tracking log of this program.

68-020	2024-01-01	00:00	ToO			Missed due to telescope being closed because of high humidity.	Failed
68-020	2024-01-02	00:38	SoftToO	GRB240102A	ALHa020051 - ALHa020058	The target was observed almost as soon as it was possible giving the conditions.	Observed

68-020	2024-02-24	00:51	ToO	epw20240219aa	ALHb240054 - ALHb240065	Observed with clear skies, airmass around 1.2-1.3, seeing between 0.7-1.5 arcsec.	Observed
68-020	2024-02-26	03:30	ToO	GRB240225B	ALHb260055 - ALHb260057, ALHb260135 - ALHb260147, ALHb260148 - ALHb260151	Successfully observed to the best of our knowledge and capabilities. Thin clouds, airmass of 1.2, seeing of around 0.7 arcsec. We did notice that the object was quite faint in the slit, which might have affected observations. We hope nonetheless they turned out good. Instructions on how to take spectroscopy with alfosc was pretty unclear. Due to this, the ToO took longer time to complete than what is indicated, since we had to figure it out on our own. In general, we felt like the instructions for how to handle this was very poor, and that the support astronomer were not really supportive, and we suggest that the NOT include clearer introductions and instructions on what to do when getting a spectroscopy with alfosc ToO.

68-020	2024-02-27	00:19	ToO	GRB240225B	ALHb270092 - ALHb270094	The observation had to be stopped due to extremely high wind. The files produced had a total duration of 669 s.	Failed
68-020	2024-02-28	00:23	ToO	grb240225b	ALHb280205 - ALHb280207	Clear skies, seeing of around 2	Observed
68-020	2024-03-01	00:00	ToO			No observations have been done due to bad weather	Failed
68-020	2024-03-18	02:28	ToO	EP240315A	ALHc180279 - ALHc180305	Hannu Parviainen and Judith Korth observed the ToO on the night of 18.03.2024. We had to start the script twice because the telescope focus was quite off at the first try (our observations were carried out heavily defocussed so we didn't care to focus the telescope at the beginning). The seeing was not great but otherwise everything went well after focusing the telescope. The observations lasted significantly longer than what we expected, but we didn't want to quit the script in the middle.	Observed

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