Abstract

A summary of EGRET observations of PKS 0528+134 is given, with special emphasis on the 1993 March observations when the source flared in gamma-rays. The flux history of PKS 0528+134 as well as spectra of the source are presented. Multiwavelength observations of PKS 0528+134 during the flare are also given. A detailed relativistic SSC jet model agrees well with the 1993 March multiwavelength spectrum. However, the data are insufficient to discriminate between this and other emission models.
