Scientific paper

The far ultraviolet photometer on board the Prognoz-6 satellite measured the brightness distribution in the 584 A line of atomic helium in interplanetary space. Since atoms of neutral helium penetrate deeper into the solar system than neutral hydrogen and are focused by the Sun's gravitational field, it is possible to determine the direction of the vector Vw, which is the sum of the interstellar gas velocity vector Vt and the vector -Vs which is the velocity vector of the Sun relative to several hundreds of the closest stars. The scanning geometry of the photometer system is illustrated graphically and the data from seven observational sessions between 29 Sep. 1977 and 15 Jan. 1978 are summarized in tabular form. The velocity vector projected onto the celestial sphere (Vs) has a right ascension of 77 plus or minus 2 deg and a declination of 17 plus or minus 2.5 deg.
