Observations by the solar vector magnetograph of the Okayama Astrophysical Observatory.
Abstract
The vector magnetograph of the Okayama Astrophysical Observatory has been in operation since the fall of 1982. The instrument, operation, and data reduction are described briefly. Some observations of the development of a small active region, a flare, and azimuths of the magnetic field relative to the Hα fine structure are reported. The accuracy of the measurement is limited by the incident photon number and as good as 0.1 % in the degree of polarization.
