search_local_solar_eclipse

Searches for the first solar eclipse visible at a specific location on Earth's
surface that occurs after the given start time. Note: an eclipse reported by
this function might be partly or completely invisible due to the time of day.
To find a series of eclipses, use <code>next_local_solar_eclipse</code> with the
<code>peak</code> time from the previous result.

Provides access to the 'Astronomy Engine' C library
(<https://github.com/cosinekitty/astronomy>) by Don Cross. The library
calculates positions of the Sun, Moon, and planets, and predicts
astronomical events such as rise/set times, lunar phases, equinoxes,
solstices, eclipses, and transits. It is based on the 'VSOP87' planetary
model and is accurate to within approximately one arcminute. This package
bundles the single-file C source so that other R packages can link against
it via 'LinkingTo' without shipping their own copy.
