✦ Synopsis


The results of the spectrophotometrical measurements of the polarization in the coronal lines Fe xIv 5303 fit and Fe x 6374 fit are given. Polarization spectrograms were obtained by two spectrographs (prism and echelle types) during the solar eclipse in Mexico on 7 March, 1970 near the region of the second contact at the heights 0.06 to 0.12 R| above the limb. The polarization in the green line is about 30 % (for averaged height 1.08 Ro). The polarization in the red line is close to the errors of the measurement and does not exceed 6 % A brief discussion of the results is also given.

By means of a photographic polarimeter, we attempted to measure both the amount and direction of linear polarization of all emission lines between 3400 and 9000 A~ in the inner corona (l.034<<\_r/ro < 1.085). Only the green and red coronal lines have been analyzed in detail. Neither of these lines s

A 5303 A-photometer was constructed for the 20 cm coronagraph of the Wendelstein solar observatory. Details of the photometer, the method of measurement and an example for measured isophotes are given. The Wendelstein photometer is compared with the 5303 A-Sac Peak photometer.
