We report on a ongoing campaign of multiwavelength observations of the superluminous galactic object η Carinae, following its mid 1992 low state. The BeppoSAX LECS and MECS observations of December 1996 detected many sources in the η Car field. η Car itself is by far the brightest, with a multi-component spectrum. The object was in a high state in agreement with ASCA and RossiXTE observations. Optical (LNA), ultraviolet (IUE), and radio observations indicate a general flux modulation following the 5.52y cycle. A gradual decrease of these fluxes since 1995 are suggestive of the approaching of the next low state.
