Simultaneous multifrequency observations of 3C 279 extending
from the radio to the gamma ray range are presented.
These are part of an extensive campaign coordinated with the
GRO pointing of 3C 279 from mid-December 1992 to mid-January 1993, when
3C 279 was in a low state.
A comparison with previous simultaneous
observations obtained in 1991 shows that above $10^{14}$ Hz where the
frequency coverage is good, the source faded
in all bands. The largest variation occurred in the
gamma ray flux, supporting inverse Compton models for the gamma ray production.
