SRG discovery of SRGA J204318.2+443815 = SRGE J204319.0+443820 - possible Galactic X-ray transient
Abstract
On Nov 20, 2020 during the second ongoing survey, the Mikhail Pavlinsky ART-XC telescope on board the SRG observatory discovered a bright X-ray source at RA= 310.8259, Dec=44.6374 (J2000) with a 90% error radius of 25". The source was registered with the X-ray flux of about 1.7 mCrab (~2.4x10-11 ergs cm-2 s-1) in the 4-12 keV energy band.
