NASA NTRS1973

Simultaneous electrophotometric and spectral observation of N Del 1967

Eleven spectrograms of low dispersion and more than sixty observations in the UBV system are obtained. The light of the nova is found to be unchanging except for J. D. 2439703. With the increase of (B-V) both (U-B) and spectrophotometric temperature decreases. An attempt was made to connect the light variation with the ones in the continuous spectrum.

NASA NTRS1973

An electrophotometer operating in a photon-counting regime

A photon counter photometer constructed allows one to carry out the UBV - photometry of stars from 6.0 to 14.0 stellar magnitude with the accuracy of 0.007 to 0.017 stellar magnitude. The absorption coefficients in U, B, V are determined and the color equations for transferring the observed magnitude differences to the UBV system are found.
