Sky & Telescope - November 2020 - 47

Neptune transits the meridian one
or two hours after the end of evening
twilight, and Uranus transits late in
the evening. (A Neptune ﬁnder chart
appeared in the September issue on page
48; for a Uranus ﬁnder chart, turn to
page 51 of the October issue.)
Pluto is a challenging, 14.6-magnitude speck located just 41′ south of Jupiter on the evening of the 12th. (For a
Pluto chart see the July issue, page 48.)

Mercury is at greatest elongation
on November 10th, when it's 19° west
of the Sun and is visible more than 90
minutes before sunrise. By this date,
the planet has brightened to magnitude
-0.6. Even at month's end, Mercury still
rises almost an hour before the Sun.

The waning crescent Moon is attractively placed 6° above Venus on the
morning of the 12th, and on the 13th
it's between Venus and Mercury, form-

ing a lovely pattern that includes nearby
Spica. In the evening sky, the waxing
lunar crescent skips past Jupiter and
Saturn on the 18th and 19th, then, as a
waxing gibbous, lies a few degrees below
Mars at nightfall on the 25th.
The Moon undergoes a penumbral
eclipse visible all across North America
in the predawn or dawn hours of
November 30th (see page 48 for details).

PRE-DAWN AND DAWN
Venus and Mercury put on a very
interesting dawn performance this
month. Venus dims and shrinks a bit,
but it remains high in the east-southeast during morning twilight. The magnitude -3.9 dazzler rises almost 3 hours
before the Sun as November begins, but
less than 2½ hours before sunrise as the
month ends. Mercury is visible for the
entire month, though initially it shines
a relatively modest magnitude 1.6. If
you've never seen Mercury as a tiny
crescent, this is your chance. On the
2nd, the planet rises well over an hour
before the Sun, and its 21%-illuminated
disk has a diameter of 8.6″ - not much
smaller than gibbous Venus's 13.0″.
Also on the 2nd, Mercury is 4° to the
left of the similarly bright Spica. Venus
has its own encounter with Spica on
