Chenyu Wang and Zirui Yang report on behalf of the GRID Collaboration:

GRID-03B and GRID-04, onboard the same CubeSat, report the detection of the long-duration GRB 230827A, which was also detected by Fermi/GBM, Swift/BAT-GUANO, GRBAlpha, VZLUSAT-2, Glowbug and INTEGRAL/SPI-ACS (GCN 34575, 34582, 34583, 34588, 34603).

The event was triggered with GRID on 2023-08-27 at 18:17:41 UTC. The GRID light curve shows a three-pulse temporal structure. The measured burst duration (T90) in the 30-2000 keV range is approximately 57.8 ± 6.1 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.
