Session 23 - High Luminosity AGN and QSOs.
Oral session, Monday, June 10
During the first 5 days of a scheduled 2-week observation of 3C 279 by the Compton Gamma Ray Observatory (CGRO) 16-30 January, 1996, the object was found to be in a high gamma flux state in the EGRET (high-energy) band; a ToO extension of 1 week was therefore implemented. 3C 279 remained generally bright during most of the scheduled 2 week observation, with significant upward and downward excursions. During the third (extension) week, it flared to the highest level ever observed from it in gamma-rays, comparable to the large flare from PKS 1622-297 in 1995 June. The EGRET observations were part of a large campaign of multiwavelength monitoring, with the goal of determining the time delays in correlations between various frequency bands, as well as time-resolved spectral changes. The gamma-ray light curve will be presented along with a sample of the multiwavelength data obtained during the flare.
