Abstract

During 1932-33 and 1952.53 periods of predominantly recurrent magnetie activity, application of appropriate low-pass and band-pass numerical filters to time series of daily indices, Ap, has been made to examine the magnitude of 27 -day recurrence and to Isolate the recurrent activity. The number of solar centres or activity the solar hemispheres of these centres, their probable latitudes and the approximate angles of the corpuscular streams have been inferred from the filtered time series.
