The Fermi GBM team reported detection of GRB 240912A in GCN 37465. We analyzed the INTEGRAL SPI ACS data around the given T0 and detected a multi-peak burst. The light curve is given on the following link and further outcomes will be updated on the same page. The SPI ACS is sensitive above 80 keV; the burst peaks at ~4200 counts/s above a steady rate of 3400 counts/s, this may be affected by the instruments orientation with respect to the direction of the source.

This work is based on observations with INTEGRAL, an ESA project with instruments and a science data center funded by ESA member states (especially the PI countries: Denmark, France, Germany, Italy, Switzerland, Spain), and with the participation of Russia and the USA. The SPI-ACS detector system has been provided by MPE Garching/Germany.
