This happens at around the time when the Moon's orbit carries it around the far side of the Earth as seen from the Sun, at around the same time that it passes full moon.
This distance between the Earth and Moon will be 0.0027 AU (404,000 km).
The exact positions of the Sun and Moon in the sky will be:
|Object||Right Ascension||Declination||Constellation||Angular Size|
The coordinates above are given in J2000.0.
