P73-016: Probing the Geometry of Fast Extragalactic Transients

P.I.:Tom Reynolds

This is a ToO and SoftToO program using ALFOSC

Requested setups:

  • Grism #4
  • Slit_1.0, Slit_1.3
  • Lin-Pol-imaging

Observing instructions:

When an observation is triggered, OBs will be made and submitted to the Queue:
  • In a sequencer window type cd ~/scripts/73-016/
  • Look for the most recent scripts with ls -lrt and execute them
  • Remember to update the OBs and send the SoftToO report

73-016 2026-04-11 00:42 SoftToO 2026ezk ALJd110081 - ALJd110084 Observed under clear skies and sub-arcsec seeing. Observed
73-016 2026-04-15 00:43 ToO 2026joh ALJd150122 - ALJd150131 Both Obs ran with clear skies and good seeing. Observed
73-016 2026-04-21 00:40 ToO 2026joh ALjd210145 through ALjd210150 Observations performed after moon had set. The science exposure extended 6 min into twilight. An error appeared when running the HeNe arc calibration exposure following the science exposure - the error said that a Ne lamp did not turn on. Looking at the HeNe arcs they look fine, though. However, we started getting errors about XPA communication w/ ALFOSC failing. Tried restarting obsys, but same error(s) appeared repeatedly and we were not able to execute the observations of the standard star for this ToO. Observed

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

Should any of the observations have been carried out using the OB system, you will find additional information HERE
