Abstract

THE purpose of this communication is to direct attention to some ionospheric phenomena observed during the period of the above flare and during the early part of the associated geomagnetic storm that ensued on September 30, 1961. The flare, which was of importance 3+, was first detected around 2200 U.T., and the intensity of the Hα radiation reached a peak near 2224 U.T. all on September 28. The magnetic sudden commencement over North America occurred between 2108 and 2109 U.T. on September 30.
