X-radiation was measured coincidently with other cosmic radiation from solar flares observed on Oct. 12, 1960. Measurements were taken from a baloon that reached a peak altitude of 1.2 x 10/sup 5/ ft. Two events were recorded on the x-ray scintillation counter, one at 1730 UT and the other at 1747 UT. Sudden enhancements of atmospherics, sudden cosmic noise absorptions, and radio noise storms that occurred during this time period were described. (T.F.H.)
