Description
Summary:At the solar total eclipse of 1997 March 9, we made a series of photographic observations of the solar corona in Mohe City (Xilinji), Heilongjiang Province. On images taken with different exposures, there are many characteristic coronal structures including long and broad coronal streamers in both east and west equatorial regions, plumes containing over 20 polar rays as well as coronal holes in both south and north polar regions. Comprehensive results of measurements of the structures and brightness in the coronal images, and of the morphology and structures, and isophotometric contours and brightness profiles in both east and west equatorial regions and both south and north polar regions are presented.
