We searched for a corresponding counterpart in the INTEGRAL/SPI-ACS data. In an SPI-ACS light curve above 80 keV, we find a signal temporally coincident with the GBM detection, having an approximate duration of ~ 40 sec. The signal consists of two pulses over this duration. The approximate peak count rate in SPI-ACS is 67,700 cts/s for E>80 keV, over a median background rate of 63,324 cts/s. This work is based on observations with INTEGRAL, an ESA project with instruments and a science data centre funded by ESA member states (especially the PI countries: Denmark, France, Germany, Italy, Switzerland, and Spain), and with the participation of Russia and the USA. The SPI-ACS detector system has been provided by MPE Garching/Germany. ----- (a) INAF/IAPS-Rome (b) ICSC National Research Centre for High-Performance Computing

Dasgupta et al., GCN #39267) and INTEGRAL/SPI-ACS (P. Barria et al., GCN #39268). With the event-by-event data downloaded through the X-band ground station, the GRM light curve shows that this burst consists of multi-pulses with a T90 of 32.54 +/- 3.62 s in the 15-300 keV band. In addition, the position of this burst, as determined by Fermi/GBM (GCN #39262, RA: 150.3 deg, DEC: -25.5 deg, Error: 2.8 deg), is located at about 52 degrees from the SVOM optical axis, and outside the ECLAIRs field of view.

The detection was confirmed at the peak time 2025-02-10 05:32:02.5 UTC. The T90 duration measured by GRBAlpha is 22.5 s and the overall significance during T90 reaches 11.8 sigma. The light curve obtained by GRBAlpha is available here: https://grbalpha.konkoly.hu/static/share/GRB250210A_GCN.pdf All GRBAlpha detections are listed at: https://monoceros.physics.muni.cz/hea/GRBAlpha/ GRBAlpha, launched on 2021 March 22, is a demonstration mission for a future CubeSat constellation (Werner et al. Proc. SPIE 2018). The detector of GRBAlpha consists of a 75 x 75 x 5 mm3 CsI scintillator read out by a SiPM array, covering the energy range from ~50 keV to ~1000 keV. To increase the duty cycle and the downlink rate, the upgrade of the on-board data acquisition software stack is in progress. The ground segment is also supported by the radio amateur community and it takes advantage of the SatNOGS network for increased data downlink volume.
