Swift XRT follow-up observations of the flat spectrum radio quasar 3C 345
Abstract
Following the flaring activity observed (ATel#15313) from a gamma-ray source positionally consistent with the flat spectrum radio quasar 3C 345 (4FGL J1642.9+3948, (Abdollahi et al. 2020, ApJS 247, 33), with radio coordinates (J2000.0), R.A.: 250.745041 deg, Dec.: 39.810276 deg (Johnston et al. 1995, AJ, 110, 880) and redshift of z=0.5928 (Marziani et al. 1996, ApJS, 104, 37) we requested a high-urgency Swift target of opportunity multiple observation.
