INTEGRAL simultaneous upper limits on the Fermi-LAT Galactic plane transient
Abstract
The field region of the Fermi-LAT transient, recently detected on the Galactic plane (ATel #14299) at coordinates R.A.=23.02 deg, Dec=59.39 deg (J2000), has been covered by simultaneous INTEGRAL Galactic Plane Scans (GPS) observations from 30 Dec 2020 02:15 (UTC) to 1 Jan 2021 06:15 (UTC) for a total on-source time of about 12 ks. No source was significantly detected by IBIS/ISGRI inside the Fermi-LAT error circle, we inferred 2-sigma upper limits of 3 mCrab (2.7 x 10-11 erg cm-2 s-1) and 7.7 mCrab (3.8 x 10-11 erg cm-2 s-1) in the energy bands 25-60 and 60-100 keV, respectively.
