     OBSERVATIONS OF PULSATING RADIO SOURCE CP 1919+22.


The observations were made with the 2,6-meter Crimean Astrophysical Observatory
telescope. On March 29, 1968 prime focus plates of a star identified with the
"pulsar" were obtained with an image tube and filters of effective wavelengths
lambda lambda 4800, 5060, 6565 and 7400. On April 22, 23 and 24, 1968 spectra
with dispersion 250 A/mm were obtained with an image tube spectrograph
(exposure was 1,5-2 hours). The spectral resolution was about 10 A. With this
resolution no details were found in the spectra. A continuous energy
distribution of the "pulsar" derived from the spectrograms and filter plates
was similar to that of a M-type star. The observed energy distribution
apparently is strongly modified by interstellar absorption.
