The Moon will make a close approach to the Sun in the sky
as it sweeps along its eastward path across the night sky. As it does so, it
will draw too close to the Sun for observation, passing within a mere
04°13' of it in the constellation Sextens.
As a result of the Earth, Moon and Sun all lying in a straight line in the
Solar System, with the Moon in the middle, we will also see almost exactly the
opposite side of the Moon to that which is illuminated by the Sun, meaning
that it will appear almost completely unilluminated.
Since the Moon moves quite quickly across the sky – by nearly 15°
per day – it will not be hidden by the Sun's glare for long. Over
subsequent days, the Moon will become visible in the late afternoon and dusk
sky as a waxing crescent. By first quarter, a week after new moon, it will be
visible until around midnight.

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 from the DE405 ephemeris published by the Jet Propulsion Laboratory (JPL).
