TITLE: GCN CIRCULAR NUMBER: 39907 SUBJECT: EP250302a: SPI-ACS/INTEGRAL Upper Limit DATE: 25/03/28 13:40:48 GMT FROM: Alexei Pozanenko at IKI, Moscow P. Minaev (IKI), A. Pozanenko (IKI), S. Grebenev (IKI), I. Chelovekov (IKI) and IKI GRB-FuN We searched the INTEGRAL dataset for gamma-ray emission from the X-ray transient EP250302a, detected with WXT EP (Dai et al., GCN 39556). No significant excess above the background was detected during the EP250302a in any of the detectors. The source EP250302a is located 71 degrees off-axis of the INTEGRAL telescopes' field of view. In particular, for the SPI-ACS detector, the upper limit (3-sigma) for the fluence from an event with a duration of 100 sec (during the first and second EP250302a episodes) is 3.2e-6 erg*cm^-2 using the softest simulated CPL spectrum with Ep = 20 keV. The SPI-ACS estimating is based on the calibration given in the paper https://ui.adsabs.harvard.edu/abs/2023MNRAS.525.2411M We thank the INTEGRAL Observatory and all the staff who have served it for over 22 years. Blessed be the memory of its deeds.
