Abstract:

Records of solar x-ray emission during the Apollo 8 manned lunar-orbiting mission show only one significant x-ray event. Comparison of this event with other large flares shows that it is completely overshadowed by two huge flares which occurred in July 1968. Events as large as those of July 1968 must be considered possible during the next year or two. Author
