International Program on Solar‐Terrestrial Physics

With the sun waxing out of its quiet years into a period of maximal activity, an international program on solar–terrestrial physics is replacing IQSY, the International Quiet Sun Year program of, 1964–65. Herbert Friedman, head of atmospheric and astrophysics at the US Naval Research Laboratory, is president of the organizing commission, and Edward R. Dyer, a National Academy of Sciences astronomer, has recently taken over secretary duties. 12 projects are in progress under 12 chairmen. Ten nations are represented by the 29 commissioners and two alternates.
