Abstract: Photometric monitoring of η Car over the last 32 years shows secular, periodic and quasi-periodic variations at near-infrared wavelengths. Most of the flux at JHKL is free-free emission from the central star and its immediate surrounds; only at L is there a possible contribution from hot dust. The L-band and X-ray flux show a remarkable degree of similarity in the morphology of their light curves at the time of the spectroscopic events.
