P70-507: The new populations of gamma-ray bursts revealed by SVOM and Einstein Probe

PI: Daniele Bjorn Malesani, Johan Peter Uldall Fynbo, Dong Xu



ALFOSC/StanCam+NOTCam ToO program with override status

ToO triggers have override status.

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/70-507/.

For the observer:

Go to the directory
  cd ~/scripts/70-507
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.

In the case of NOTCam, make sure that differential skyflats are obtained for the camera and filter setup that is requested.

Remember to fill the ToO tracking log of this program.

70-507 2024-11-01 00:33 ToO GRB241029A ALHk010091 - ALHk010095 Clear skies, seeing around 0.6 arcsec Observed
70-507 2024-11-02 00:53 ToO GRB241030A ALHk020079 - ALHk020086 Thin cloud cover at the beginning of the observation, cleared up after the first exposure. Average seeing around 1 arcsec. Observed
70-507 2024-11-03 01:28 ToO GRB241029A, GRB241030A ALHk030069 - ALHk030076 Thin clouds ans sub-arcsec seeing Observed

70-507 2024-11-28 00:38 ToO GRB241128A ALHk280046 - ALHk280053 Observed target in clear skies with seeing around 2.3" Observed
70-507 2024-12-08 00:18 ToO GRB241209a ALHl080069 - ALHl080071 Observed
70-507 2024-12-17 01:43 ToO GRB241217A,GRB241218A NCHl170242 - NCHl170259,STHl170021 - STHl170029,STHl170030 - STHl170037 Struggling with clouds, some of the J-band images of GRB241217A suffer from clouds. Observed
70-507 2024-12-28 00:46 ToO GRB241228A GRB241228B ALHl280097 - ALHl280104, 129-130 very bad seeing Observed

70-507 2025-01-02 00:52 ToO grb250101a ALIa020071 - ALIa020079 Seeing around 0.6 arcsec, and clear skies Observed
70-507 2025-01-03 01:47 ToO grb250103a (+ sp0644+375) ALIa030141 - ALIa030157 The target had peak altitude in the very start of night, but could not be observed right after sunset due to very heavy clouds. The target was observed when the conditions improved - thin clouds and sub-arc seeing. For the spectroscopy, the last 3 exposures were outside the requested LST range, due to above described conditions. Taken time-criticality into consideration, a decision was made to proceed with the observation in sub-optimal LST range. Observed
70-507 2025-01-05 00:00 SoftToO grb250101a ALIa050003 - ALIa050011 Observed on NBI guaranteed time 70-802 voluntarily - therefore time set to 0. Reported as observed. Observed
70-507 2025-01-06 00:41 ToO GRB250106A ALIa060237 - ALIa060246 good seeing Observed
70-507 2025-01-08 00:41 ToO GRB250108A ALIa080175 - ALIa080184 Great night with excellent conditions. Low wind, humidity and good seeing. Target observed at the requested time of 3am (around 28 deg alt) Observed
