Abstract: | Two distinct types of centimeter solar bursts, classified simple, have been identified and related to the position (with respect to a sunspot) of the related flare. Type S in which the flare occurs directly over the spot has a radio spectrum with a maximum beyond 10 GHz, type P which occurs away from the spot has its maximum occurring near 3 GHz. Considering the structure of the spot magnetic field and invoking the synchrotron effect, it is shown that the origin of the radio burst may be attributed to a burst of energetic electrons with an energy peak near 3 MeV. |
