The Neil Gehrels Swift Observatory detection of hard X-ray outburst from Cygnus X-3
Abstract
We report the detection of new hard X-ray outburst from Cygnus X-3 using the Burst Alert Telescope (BAT) on the Neil Gehrels Swift Observatory. The BAT flux (15-50 keV) reached 0.24 Crab (0.054 & plusmn;0.003 counts/cm2/sec) on MJD 59213 (30th December 2020) which is highest since the outburst of the source in October 2019.
