Аннотация:We present the result of the IR photometry of Nova Del 2013 obtained at the Crimean Station (Nauchny, Ukraine) of the Sternberg Astronomical Institute. JHKLM photometry was carried out with 125-cm telescope using a InSb-photometer on:
September 21.8 UT: J=5.88, H=5.85, K=5.03, L=3.68, M=3.26
September 27.8 UT: J=6.15, H=5.64, K=4.46, L=2.87, M=2.42.
BS7635 (J=0.79, H=0.03, K=-0.16, L=-0.36, M=-0.08) was used as a standard star. The observational errors do not exceed 0.03 for all bands.
K-L and L-M color indexes correspond to a warm dust envelope with Tdust of the order of 1000 K.
