3He is an intermediate product in the proton-proton chain, and standard models of the Sun predict a large bulge of enhanced 3He abundance near Mr/M o = 0.6 in the contemporary Sun. The relatively low abundance of 3He at the solar surface, which is derived from solar wind observations, poses severe c

Periods of very low solar wind velocity at 1 AU, during the interval from 1977 to 1983, are identified and mapped back to the coronal source surface at 2.5 R o. In total 25 such low-velocity events were found. Inferred source locations were characterized with respect to their position relative to th
The existence of a long-term variation, related to the solar activity, of the average a-particle abundance in the solar wind has been suggested by Robbins et al. (1970) and recently confirmed by Bollea et al. (1972) andOgilvie (1972). Hirshberg et al. (1972b), comparing the distribution of the a-par
