Arguments
k
k The same K term as returned from CAAMoonPhases::K. For a solar eclipse, this value should be a value without any decimals as a solar eclipse refers to a New Moon .
Value
A struct containing the following values:
bEclipse true if a solar eclipse occurs at this New Moon.
TimeOfMaximumEclipse The date in Dynamical time of maximum eclipse.
F The moons argument of Latitude in degrees at the time of the eclipse.
u The U term for the eclipse.
gamma The gamma term for the eclipse.
GreatestMagnitude The greatest magnitude of the eclipse if the eclipse is partial.
