Abstract

The blazar 3C 279, one of the brightest identi\DHed extragalactic objects in the c-ray sky, underwent a large (factor of D10 in amplitude) \~Nare in c-rays toward the end of a 3 week pointing by Compton Gamma Ray Observatory (CGRO), in 1996 January\`EFebruary. The \~Nare peak represents the highest c-ray intensity ever recorded for this object. During the high state, extremely rapid c-ray variability was seen, including an increase of a factor of 2.6 in D8 hr, which strengthens the case for relativistic beaming. Coordinated multifrequency observations were carried out with Rossi X-Ray T iming Explorer (RXT E), Advanced Satellite for Cosmology and Astrophysics (ASCA; or, Astro-D), Roentgen Satellite (ROSAT ), and International Ultraviolet Explorer (IUE) and from many ground-based observatories, covering most accessible wavelengths. The well-sampled, simultaneous RXT E light curve shows an outburst of lower amplitude (factor of \^
