Abstract:
Structures of the white-light corona (WLC) as were observed during last
total solar eclipses on March 9, 1997 and February 26, 1998 are discussed. Both
eclipses occurred in the minimum of cycle activity at the beginning of cycle
23. The WLC was a minimum type with many polar rays and extended helmet
streamers, located in middle heliographic latitudes or very close to the
equator, and coronal holes around the poles. Flattening index is derived, and
turn out to be, a+b = 0.27 for 1997, and a+b = 0.22 for 1998, respectively.
