“…Data collection ended at T 0 + 137 ks (2022-10-11 03:18:20), before the entrance into the radiation belts. Subsequently, observations during two more revolutions (2559 and 2560) were performed, from T 0 + 176 ks to 299 ks (2022-10-11 14:08:20 to 2022-10-13 00:18:20) and from T 0 +459 ks to 572 ks ( 2022-10-14 20:45:00 to 2022-10-16 04:08:20) Unfortunately, due to angular momentum constraints (see Kuulkers et al 2021), INTEGRAL could not stay on target continuously, so it was only able to observe the target for 58% of the time in the quoted time period.…”

The gamma-ray burst GRB 221009A is among the most luminous of its kind and its proximity to Earth has made it an exceptionally rare observational event. The International Gamma-ray Astrophysics Laboratory ( INTEGRAL ) was in an optimal aspect position to use its all-sky instruments for recording the prompt emission and early gamma-ray afterglow in unprecedented detail. Following the initial detection, a swiftly scheduled follow-up observation allowed for the hard X-ray afterglow time and spectral evolution to be observed for up to almost a week. The INTEGRAL hard X-ray and soft gamma-ray observations have started to bridge the energy gap between the traditionally well-studied soft X-ray afterglow and the high-energy afterglow observed by Fermi /LAT. We discuss the possible implications of these observations for follow-ups of multi-messenger transients with hard X-ray and gamma-ray telescopes.
