摘要：

Observational infrared (IR) and optical data are presented of the newly discovered Be/X-ray binary system LSI + 61-degrees 235, taken over the period 1991 August-1992 May. Though the IR shows little evidence for any changes, the optical Halpha spectrum has undergone substantial modification. Combination of optical photometric measurements with the IR photometry allows the overall spectrum to be investigated and the existence of the Be star's circumstellar disc to be directly confirmed.
