A study of the histories of solar flares observed at 2 cm at the North Liberty Radio Observatory of the University of Iowa and observed at x-ray wavelengths with Mariner V 2-9 A and Explorers 33 and 35 2-12 A shows that post-burst increase and gradual rise and fall events are concurrent microwave and soft x-ray phenomena. Temperatures typically double during a flare. Of twenty cases studied, an F 0.5 yielded a mean peak temperature of 4 million degrees Kelvin and a mean effective diameter of 32 arc seconds. Author
