On the Observation of the Electron Corona at the Norikura Corona Station
Abstract
A K-coronameter, which is an instrument for observing the solar electron corona without an eclipse, has been mounted for operation at the Norikura Corona Station of the Tokyo Astronomical Observatory. It is found that the main component of the sky polarization which should be subtracted from the observation consists of the multiple scattsring by a molecular atmosphere. The results of some observations made in 1963 are studied in comparison with the intsnsity of green corona, prominences (dark filaments), and sunspots. The main results are (1) the values of (pB)k coincide with those given by VAN DE HULsT and (2) the coronal streamers deduced from our observations seem to coincide best with the quiescent prominences.
