This happens at around the time when the Moon's orbit carries it between the Sun and the Earth, at around the same time that it passes new moon.
This distance between the Earth and Moon will be 0.0025 AU (367,000 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.

Never attempt to point a pair of binoculars or a telescope at an object close to the Sun. Doing so may result in immediate and permanent blindness.
The circumstances of this event were computed using the DE430 planetary ephemeris published by the Jet Propulsion Laboratory (JPL).
This event was automatically generated by searching the ephemeris for planetary alignments which are of interest to amateur astronomers, and the text above was generated based on an estimate of your location.
