P68-007: Probing the Geometry of Fast Extragalactic Transients

PI: Miika Pursiainen


ALFOSC ToO + SoftToO

ToO triggers have override status, SoftToOs can trigger in Nordic Service and 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/68-007/.

For the observer:

Go to the directory
  cd ~/scripts/68-007
List the available scripts
  ls -lrt
and execute the OB generated scripts requested.

Remember to fill the ToO or SoftToO tracking log of this program.

68-007 2023-10-07 00:53 SoftToO SN2023tsz ALGj070347 - ALGj070357 I took a chance and observed the target even though the distance limit was set to 25, while it, according to Visplot was 24 degrees. I hope that it was not a hard limit. Clear skies but slightly dusty. Dimm seeing below 1.0 arcsec. Observed
