This plot shows the variation of angular separation between Moon and Sun
centers for the *Yohkoh* satellite, based upon M. Soma's calculations
from the Yohkoh orbital ephemeris of Jan. 28, 1998.
The points with asterisks show when *Yohkoh* is outside the Earth's
shadow.
The asterisks are two minute apart.
The peculiar and complicated pattern (not like your usual Kansas eclipse!)
is due to the rapid motion of *Yohkoh* in its low Earth orbit,
with an altitude fluctuating between about 500 and 800 km.
The horizontal dotted line shows the sum of the solar and lunar radii,
so that every point below corresponds to a partial eclipse.
The angular separation does not get to zero on this date, unfortunately,
so once again *Yohkoh* has missed having a total eclipse, even
though it gets three partial ones.
