X-Ray Flare in TeV-Detected Blazar 1ES 1218+304
Abstract
The TeV-detected BL Lac object 1ES 1218+304 (z=0.184) was observed 131 times by Swift between 2005 October 30 and 2023 March 31 with a total exposure of 151 ks. These observations revealed a strong X-ray variability in the 0.3-10 keV count rate between 0.47+/-0.02 cts/s and 7.18+/-0.18 cts/s with more than 10 flares by a factor of 2-4 during the densely-sampled Swift campaigns (see https://www.swift.psu.edu/monitoring/source.php?source=1ES1218+304).
