Manifestation of the 160-min solar oscillations in velocity and brightness (optical and radio observations)

All evidence of the solar origin of 160-min period oscillations is collected, and the present state of observations of this oscillation in optical and radio ranges is considered. The main results are summarized: 1) the 160-min oscillation was observed in 1981 and before; 2) an attempt to find a nonr...

Description
Summary:All evidence of the solar origin of 160-min period oscillations is collected, and the present state of observations of this oscillation in optical and radio ranges is considered. The main results are summarized: 1) the 160-min oscillation was observed in 1981 and before; 2) an attempt to find a nonradial component with l = 2 has failed; and 3) the intensity and circular polarization of radio emission show with statistical significance the presence of this 160-min periodicity.
