P72-013: Fast Blue Optical Transients from the Nordic-East Asia Network

PI: Hanindyo Kuncarayakti

ALFOSC Soft-ToO 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/72-013/.

For the observer:

Go to the directory
cd ~/scripts/72-013
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.

Remember to fill the SoftToO tracking log of this program.

72-013	2025-11-26	00:00	SoftToO			Couldn't be observed due to bad weather.	Failed

72-013	2026-02-19	02:20	SoftToO	WFST0825kfxt, AT2026dbl	ALJb190065 - ALJb190070, ALJb190209 - ALJb190214, ALJb190218 - ALJb190218	WFST0825kfxt: Started with clear skies, seeing around 2.0". Thin clouds appeared midway. AT2026dbl: Clear skies, and the seeing was around 1.5". The observing script terminated with an error after the science exposure completed, but the science frame appears good, and a HeNe arc calibration frame was therefore taken separately afterward using the same instrumental setup (filename: ALJb190218).	Observed
72-013	2026-02-21	02:18	SoftToO	AT2026dbl, hd93521, AT2026bdg	ALJb210110 - ALJb210118, ALJb210368 - ALJb210372	Observed under clear skies and good seeing.	Observed
