Cosmic-Ray Increases Produced by Small Solar Flares

Abstract

An experiment was designed to detect short-lived or small increases in the low-energy component of total cosmic-ray intensity, observe the structure, and study the correlation in time with small solar flares. The first observations of two unusually short-lived lncreases in the low-energy portion of cosmic rays measured at latitude 55- geomagnetic and altitude 45,000 ft are reported. The increases were 30% and lasted for two and three minutes. (W.D.M.)
