Chenyu Wang and Zirui Yang report on behalf of the GRID Collaboration:
The long-duration GRB 231004A (Fermi/GBM detection: GCN Circular 34795, IceCube detection: GCN Circular 34797, CALET detection: GCN Circular 34804, Glowbug detecton: GCN Circular 34812) was also detected with three GRID detectors, GRID-03B, GRID-04, and GRID-07, onboard two different CubeSats.
The event was triggered by GRID on 2023-10-04 at 08:23:35.0 UTC. The measured burst duration (T90) in the 30-2000 keV range is approximately 6.1 +/- 1.0 seconds.
GRID is a student-led project to monitor the transient gamma-ray sky with multiple detectors onboard different nanosatellites in the era of multi-messenger astronomy.
