Abstract

The data of photometric measurements of the long-period eclipsing variable epsilon Aur in the two main minima 1982 and 2010 in the spectral range of 1--5 microns are presented. Noted is the similarity of light curves in eclipse, its asymmetry, and availability of the short interval increased brightness. We are detecting the phase changing of the indicator color J-M and the effect of short-time changing of the color to be more blue at the moments during the beginning and end of the eclipse.
