Another Strong X-Ray flare in the TeV-Detected Blazar 1ES 0647+250
Abstract
The TeV-detected blazar of unknown redhsift 1ES 0647+250 has been targeted 63 times with X-Ray Telescope onboard Neil Gehrels Swift Observatory during 2010 March 6 - 2020 December 13 with a net exposure of 101 ks. During this period, the 0.3-10 keV count rate varied by a factor of ~6, and reached the value of 5.14+/-0.08 cts/s on 2019 December 3 when the source was showing a strong X-ray flaring activity since the previous month (observed mostly in the framework of our ToO requests of different urgency; see http://www.swift.psu.edu/monitoring /source.php?source=QSOB1727+502; Kapanadze B., ATel#13324).
