Non-radial unipolar coronal streamers in magnetically high latitudes and radial bipolar streamers at the magnetic equator of the Sun Original Research Article

The complex structure of coronal streamers can be better understood by their classification into two classes: non-radial unipolar streamers emanating from magnetically high latitudes, and radial bipolar streamers emanating from the magnetic equator. The coronal streamers observed during the total solar eclipses of July 11, 1991 and February 26, 1998 are classified into the two types. Various characteristics of the two types are discussed and summarized. Important relations of the two to solar, interplanetary, and terrestrial phenomena are discussed.
