- Аннотация: We present the results of the optical and IR photometry of Nova Del 2013 obtained at the Crimean Station (Nauchny, Ukraine) of the Sternberg Astronomical Institute. UBV photometry was carried out with 60-cm Zeiss telescope using a photoelectric photometer on August 15.94 UT: U=4.54+/-0.02, B=5.07+/-0.01, V=5.05+/-0.01; on August 16.80 UT: U=4.54+/-0.01, B=4.85+/-0.02, V=4.68+/-0.01; on August 16.86 UT: U=4.66+/-0.01, B=4.92+/-0.01, V=4.73+/-0.01. HD 194113 was used as a standard star. UBV magnitudes of HD 194113 (U=8.40, B=8.27, V=8.00) were determined using HD 193911 and HD 196724 as reference stars. JHKLM estimates were obtained with 125-cm telescope using a InSb-photometer on August 15.86 UT: J=4.86, H=4.79, K=4.70, L=4.38, M=4.29 and on August 16.85: J=4.20, H=4.09, K=4.05, L=3.84, M=3.83. BS7635 (J=0.79, H=0.03, K=-0.16, L=-0.36, M=-0.08) was used as a comparison star. The observational errors do not exceed 0.02 for all bands except M (in which the error is equal to 0.04). J-K color index corresponds to a F2 supergiant.
