Min. (Minimum) of Algol is the minimum brightness of
the dramatic eclipsing binary star system, Algol. It is
relatively close at a distance of 100 light years. Every
2.8 days during a 10 hour period, Algol undergoes a
major change in apparent magnitude as one of the
two stars passes behind the other. The combined
magnitude of the two stars thus dips from +2.1 to a
minimum of +3.4 halfway through the eclipse as the
second star is hidden. LX65 calculates minimum
magnitude time at mid-eclipse.
Autumn and Vernal Equinox calculates the time and
date of the fall or spring equinox of the current year.
Winter and Summer Solstice calculates the time
and date of the winter or summer solstice of the
current year.
