BASIC SOLAR RESEARCH.

Abstract

Research at McMath-Hulbert Observatory during the period Oct. 1, 1963-Sept. 30, 1964, on solar flares, solar activity and solar terrestrial relationships on the following is reviewed: Initial survey and organization of spectro-heliographic records of solar activity, 1958 1961; analysis of wavelength-sweep records for July 16, 1959, and June 25, 1960; working list of flares and daily flare index for 1963; general relationships between flares, ionospheric, and geomagnetic disturbances for 1957-1961; solar activity at start and end of first six months of the International Years of the Quiet Sun; unexpected effect related to 29.5 days in cosmic ray data; magnetic fields of large sunspots; magnetic classification of sunspots in the Mount Wilson system, 1963-64; application of hydromagnetic theory to the sun; decrease in intensity at the solar limb during the July 20, 1963 eclipse; profiles of weak iron lines; measurement for various groups of lines in the solar spectrum; relative abundances of chemical elements in the solar atmosphere.
