General information
- Name of the source: GRB240811A
- Brief description of the source:
- Object type : GRB
- Redshift (z) : ?
- Other relevant information
- RA, Dec in deg (ICRS): 226.3622, 28.8957
- Analysis by:
- Ryuji Takeishi (ICRR - take@icrr.u-tokyo.ac.jp)
Data-taking information
- Dates of data-taking: 2024-08-03, 2024-08-08
- ZD range (deg): --> 15-35 deg
- AZ range (deg): -->
- Transmission9km:
- Observation condition: dark
- Observation mode: std wobbles
- Observations:
'2024-08-03': [18412, 18413] 0.2 h '2024-08-08': [18516, 18517, 18518, 18519, 18520, 18521, 18522] 2.2 h
- Data quality selection: cosmic rates are somewhat low. None of the runs survive the default dR/dI@442pe limit of 1.5. Likely due to high dust concentration
- Joint observations with MAGIC? : yes
- Information on data-taking (observations summaries): https://www.lst1.iac.es/datacheck/observation_overview/2024/08/run_summary_2024_08_03.pdf
