P72-503: The local transient Universe

PI: E. Kankare, M. Stritzinger, T. Reynolds

ToO + SoftToO triggers with ALFOSC

Observations will be requested with ALFOSC and the OB generator will be used to request all ToO and SoftToO observations.

To summarise:

Go to the directory
cd ~/scripts/72-503
List the available scripts
ls -lrt

and execute the OB generated scripts requested in the trigger email.

For these ToO and Soft ToO triggers, please remember to fill in the ToO and SoftToO reports.

Fixed scheduled Service observations with NOTCam

The OB generator will be used to request all observations. For each night, the PI will submit OBS through the OB-generator. These OBs needs to be queued and compiled by the observer.

In order to queue the observations, enter the OB generator and click on the Queue it! button.
Then compile the scripts manually, either through the compile buttons in the OB generator or from within the OB queue.

Scripts are placed in the directory ~/scripts/72-503/ and these observations have their own EON form (i.e. no ToOMon report to fill!).
