Abstract
By use of ground based IR photometry, we have studied the dust obscuration events of the symbiotic nova RR Tel which is a binary composed of a cool mira and a hot white dwarf. The JHKL light curves were corrected for Mira pulsations and correlated to the AAVSO visual light curve. We compare the behaviour of the three obscurations in different wavelength bands and propose interpretations of the results.
