Recent SRG observations, performed during the third all-sky survey, discovered a new X-ray transient on 1 Apr 2021 (ATel #14510). The source, possibly a Galactic X-ray binary, was detected at a flux level of about 4 x 10-11 erg cm-2 s-1 (4-12 keV).
The sky region of SRGA J181414.6-225604==SRGe J181415.1-225617 was covered by INTEGRAL observations of the Galactic Center carried out a very few days later than its discovery, i.e. from 2 April 2021 at 06:32 UTC to 3 April 2021 at 05:08 UTC, for a total on source exposure time of about 1.2 ks. The transient source was not detected in the energy bands 25-60 keV and 60-100 keV, the inferred
3sigma upper limits are of the order of 17 mCrab or 1.5 x 10
-10 erg cm
-2 s
-1 (25-60 keV) and 43 mCrab or 2.1 x 10
-10 erg cm
-2 s
-1 (60-100 keV). The source was not in the JEM-X field of view during the INTEGRAL observation.
