Session 56 - BL Lacs & Blazars.
Oral session, Thursday, January 08
Georgetown,
The February 1996 flare of 3C279 peaked at the highest gamma-ray intensity ever recorded for this object (Wehrle et al., submitted to ApJ). CGRO, RXTE, ASCA, ROSAT, IUE, HST, ISO and 18 ground-based observatories participated in observations at various times during January and February 1996. The CGRO EGRET and RXTE light curves are correlated during the flare without any lag larger than the temporal resolution of about 1 day. We present simultaneous spectral energy distributions prior to and near the flare peak. The gamma-rays vary by more than the square of the observed infrared-optical flux change, which poses some problems for specific blazar models.
