P70-016: Unknown mass loss at the final evolutionary stage of massive stars

PI: Takashi Nagao

ALFOSC SoftToO program

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/70-016/.

For the observer:

Go to the directory
cd ~/scripts/70-016
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 SoftToO tracking log of this program.

Proposal	Date	Time	Type	Targets	Files	Comments	Status
70-016	2024-10-01	02:42	SoftToO	SN2024kgi, SN2024ueo, SN2024qiw, SN2024gvz	ALHj010202 - ALHj010218, ALHj010239 - ALHj010246, ALHj010315 - ALHj010331, ALHj010340 - ALHj010357	The night was windy and had slightly poor seeing. However, all the observations in this proposal were successful. The spectroscopic standard Feige110 was not observed because a similar standard for grism 4 (HD19445) was observed. The files for the standard can be found in the calibration folder.	Observed
70-016	2024-10-04	00:27	SoftToO	SP1550+330, SN2024vgd	ALHj040079 - ALHj040091	Night was very tight with other higher-priority ToOs and monitoring targets. Unfortunately, there was only time to observe one target.	Observed
70-016	2024-10-05	02:19	SoftToO	SN2024knu, SN2024kmc, SN2024qzr, Feige110, SN2024gvz	ALHj050060 - ALHj050070, ALHj050081 - ALHj050090, ALHj050126 - ALHj050137	Observed in clear skies with seeing below 1.0"	Observed
70-016	2024-10-06	00:36	SoftToO	Feige110, SN2024gvz	ALHj060054 - ALHj060058, ALHj060075 - ALHj060079	Observed in clear skies with seeing around 0.9"	Observed
70-016	2024-10-11	01:37	SoftToO	Feige110, SN2024xav, SN2024xdq, SN2024qiw	ALHj110108 - ALHj110129, ALHj110133 - ALHj110149	Clear skies and sub-arcsec seeing.	Observed
70-016	2024-10-12	00:21	SoftToO	SN2024xav	ALHj120016 - ALHj120020	Clear skies and seeing around 1.6''. There will be some vignetting effects towards the end of the exposure, as the lower hatch had to be closed due to high winds.	Observed
70-016	2024-10-19	00:24	SoftToO	SN2024xeb	ALHj190133 - ALHj190137	Target observed through thin clouds and seeing of around 2 arcseconds.	Observed
70-016	2024-10-26	00:00	SoftToO			Bad weather prevented the observations	Failed
70-016	2024-10-27	00:00	SoftToO			No observations could be taken due to bad weather.	Failed
70-016	2024-10-30	03:44	SoftToO	SN2024kgi, SN2024ueo, SN2024xdq, SN2024xav, SN2024qiw, SN2024gvz	ALHj300073 - ALHj300089, ALHj300119 - ALHj300123, ALHj300145 - ALHj300199	All the data was obtained during sub-arcsecond seeing and also in good conditions with other metrics. There were minor faults related to some OBs, but all of them were fixed in the end. See more detailed comments inside the OB blocks. The standard star provided by this program was not observed, but the files ALHj300071 and ALHj300072 contain the necessary calibration which were obtained via different program but identical setup.	Observed
70-016	2024-11-03	00:56	SoftToO	SN2024xeb, SN2024yrq	ALHk030138 - ALHk030154, ALHk030160 - ALHk030163	Clear skies and sub-arcsec seeing	Observed
70-016	2024-11-13	00:58	SoftToO	SN2024aakj, SN2024qiw	ALHk130080 - ALHk130088, ALHk130139 - ALHk130147	Targets were observed in clear skies with seeing around 1.0"	Observed
70-016	2024-11-18	00:00	SoftToO			No observations could be done due to bad weather	Failed
70-016	2024-11-19	00:00	SoftToO			Targets could not be observed due to high humidity	Failed
70-016	2024-11-24	03:04	SoftToO	SN2024kgi, AT2024abup, SN2024qiw, SN2024xdq, SN2024yrq	ALHk240006 - ALHk240022; ALHk240040 - ALHk240056; ALHk240069 - ALHk240097; ALHk240103 - ALHk240111	The appropriate slits were used depending on the visibility at the time of night, but overall stayed within the 1.2 - 1.7" range.	Observed
70-016	2024-12-02	02:12	SoftToO	SN2024qzr, SN2024xav,SN2024xeb	ALHl020102 - ALHl020106; ALHl020141 - ALHl020145; ALHl020207 - ALHl020223	Targets were observed according to the seeing requirements. We had to start and stop some of the observations due to unstable seeing and clouds, so had to choose the most appropriate ones at the most appropriate times. We had difficulty finding some of your targets due to a lack of finding chart, so if this could be provided in the future then we can make sure that we observe exactly what you are looking for! :)	Observed
