P73-012: 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/73-012/.

For the observer:

Go to the directory
cd ~/scripts/73-012
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.

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