TITLE: GCN CIRCULAR NUMBER: 37519 SUBJECT: GRB 240916A INTEGRAL SPI ACS LIGHT CURVE DATE: 24/09/16 05:27:32 GMT FROM: Devraj Pawar at R. J. College, Mumbai - 86, India <devrajdp@gmail.com> Devraj Pawar (R. J. College, Mumbai-86, India) on behalf of a collaboration studying transients. The Fermi GBM team has reported a GRB in GCN 37518. We analyzed the INTEGRAL SPI ACS data around the T0 given in GCN 37518 and detected a peak in the count rate which lasts for about 50 s. The SPI ACS is sensitive above 80 keV; the peak of the burst is at ~4300 counts/s and the steady rate preceding the event is around 3800 counts/s. The peak count rate may be affected by the instruments orientation with respect to the direction of the source. The light curve and the profile is given in the link below : [https://docs.google.com/document/d/1ypksdTUoXwB8_Lwr5zhiB-8ivEdobW_oeGTxN8B2Y_Y/edit?usp=sharing]() 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.
