Compton Telescope Observation of Gamma-Ray Flare from Quasar PKS0528+134

The quasar PKSO528+134 was observed to flare by the energetic gamma-ray experiment (EGR-ET) γ-ray telescope on the Compton gamma-ray observatory during the viewing period 213 (VP213). The Compton telescope data from VP213 have been reanalyzed by using the direct demodulation method. Images of the source are obtained at energies above 3 MeV and the time variability in the energy range 10-30 MeV is consistent with the result of EGRET. There is no spectral break at energies above 3 MeV during the flare.
