摘要：
Following the initial detection of 3C 279 as an intense high-energy gamma-ray emitter during a 1991 June 16-28 observation, the EGRET instrument on the Compton Gamma Ray Observatory made a second observation during 1991 October 3-17. Low-sensitivity observations were also made during 1991 October 12-31 and 1992 April. The relatively intense June fluxes allowed the time structure to be determined down to the level of half-days. During this period a flux enhancement of about a factor of 4 is seen, lasting several days. The October exposures show fluxes somewhat below the minimum June flux, with no significant evidence of time variability. The 1992 April fluxes are well off the main instrument axis, and so the statistics are less compelling, but the evidence appears to show additional time variability. The observations are consistent with a model in which the gamma rays result from Compton scattering of low-energy photons by relativistic electrons in a jet.
