P69-018: Flares or changing-states? - A pilot study of black hole transients

PI: S. Raimundo

This is a Monitoring program using ALFOSC spectroscopy with Gr# 7 and 8 and the Slit_0.5" wide slit.

Instrument setup:

  • ALFOSC: Gr #7, Gr #8, 0.5'' slit

Daytime calibrations:

  • alfosc.alfosc-calibs AL**** in the morning after the observations.

The OB generator will be used to request all observations.

For the observer:

Go to the directory
  cd ~/scripts/69-018
List the available scripts
  ls -lrt
and execute the OB generated script for the appropriate date as requested.

ALHd150056 - ALHd150059, ALHd150089 - ALHd150102 The standard star Feige56 was observed at the beginning of the night, and the rest of the targets were observed in the middle of the night. The preference to observe the standards before the science target wasn't obeyed as there were higher priorities to follow in scheduling. Seeing was around 1.5'' during every target. Observed
69-018 2024-04-28 00:00 Mon Failed because telescope could not be opened due to high humidity and subzero temperatures. Failed
