We present the results of a multiwavelength monitoring campaign targeting the c-ray source 2CG 135]1 in an attempt to conÐrm the association of this object with the radio/Be/X-ray binary system LSI ]61¡303. The campaign included simultaneous radio, optical, infrared, and hard X-ray/c-ray observations carried out with a variety of instruments, covering (not continuously) almost three binary
cycles of LSI ]61¡303 during the period 1994 AprilÈJuly. Three separate OSSE observations of the
c-ray source were carried out, covering di†erent phases of the radio light curve. Hard X-ray/c-ray emission was detected from the direction of 2CG 135]1 during the Ðrst of these OSSE observations. The signal-to-noise ratio of the OSSE observations was insufficient to establish a spectral or intensity correlation of the high-energy emission with simultaneous radio, optical, and infrared emission of LSI
]61¡303. We brieÑy discuss the theoretical implications of our observations.
