UBVJHKLM PHOTOMETRY OF NOVA-CYGNI 1992

We present the results of the photometric UBVJHKLM observations of Nov a Cygny 1992 performed at the period from the 83rd to 290th day after the nova's outburst. Against the background of gradual decline of the radiation flux over the central and the blue region of the visible spe ctrum according to the law of t-1.5, we noticed, during the nova's evo lution, a period of the violet brightness' constancy during which the nova's (U-B) color index reached the extremely low value equalled -1m. 8. After the outburst, 190 days later, we revealed the emergence of IR excess related to the radiation of dust grains.
