The K-coronameter developed at the High Altitude Observatory [1] to study the electron corona outside of eclipse has been in routine use since 1956 September. Up to the present date, usable observations have been obtained on some fifty-five days, and the accumulated information on the corona out to one solar radius from the limb has permitted the development of models of the electron corona above the quiet disk, the polar regions, and the active regions. The last of these, since it departs from the spherically symmetric model, should be of interest to radio astronomers.
