Some Properties of Velocity Fields in the Solar Photosphere. IV: Long Periods, Five Minute Oscillations, and the Supergranulation at Lower Layers
Abstract
Photoelectric measurements of photospheric velocity fields have been carried out with the Sacramento Peak Doppler Zeeman Analyzer. Emphasis was given to long periods and low spatial wavenumbers in deep photospheric layers, where the 5-min oscillations are less dominant.
