Abstract

Optical;X-ray;Gamma Ray;>GeV;Blazar;Quasar;Transient
We report observations of TXS 1530-131 (PMN J1532-1319) following the Fermi/LAT detection of a new gamma-ray transient coincident with the source (ATel #3579). Our analysis of the Fermi/LAT data between 2010 September 1 and 2011 September 4 shows that the source has undergone several flaring periods since 2011 June, before which the source was undetected by LAT. The source can be detected daily with TS > 25 from 2011 August 30 to September 4, indicating that the source is still flaring in gamma-rays.
