The Large Area Telescope (LAT), one of the two instruments on the Fermi Gamma-ray Space Telescope, observed a gamma-ray outburst from a source positionally consistent with the flat spectrum radio quasar 4C +01.02, also known as BZQ J0108+0135 (RA: 01h08m38.8s DEC : +01d35m00s, J2000.0, Kenneth et al. 1995) with redshift z=2.099 (Hewett et al. 1995).
Preliminary analysis indicates that on 2013 September 14, 4C +01.02 appeared in a flaring state with a daily gamma-ray flux (E>100MeV) of 1.0+/-0.2 x 10^-6 photons cm^-2 s^-1 (statistical uncertainty only), about 6 times the average flux of its gamma-ray counterpart 2FGL J0108.6+0135 (Nolan et al. 2012, ApJS 199, 31).
Because Fermi operates in an all-sky scanning mode, regular gamma-ray monitoring of this source will continue. In consideration of the ongoing prominent gamma-ray outburst, we strongly encourage multiwavelength observations of this object. For this source the Fermi LAT contact person is S. Buson (buson@pd.infn.it).
The Fermi LAT is a pair conversion telescope designed to cover the energy band from 20 MeV to greater than 300 GeV. It is the product of an international collaboration between NASA and DOE in the U.S. and many scientific institutions across France, Italy, Japan and Sweden.
