** This week's sky at a glance.

On, Sunday, tomorrow, the MOON [Lune] goes into=20
its new phase, meaning that it will rise and go=20
down with the sun  to leave some very dark nights.

On Tuesday, December 7, the sunset is the=20
earliest sunset of the year, if you live near 40=B0=20
north latitude. This is true even though the=20
longest night of the year doesn't come until=20
December 21st (the winter solstice). The=20
difference is balanced out by the year's latest=20
sunrise coming on January 4th, a similar period following the solstice.

As a heads up, make plans for the total eclipse=20
of the Moon, visible mainly in North America, on=20
the night of December 20-21. The Moon will be high in the late-night sky.


This week's planet roundup:

MERCURY [Mercure] remains in view, low near the=20
southwest horizon during evening twilight. Look=20
about 40 minutes after sunset. Mercury fades from=20
magnitude -0.4 to +0.1 this week.

VENUS [V=E9nus] blazes in the southeast before and=20
during dawn. It's still at its maximum brightness=20
(magnitude -4.8 or -4.9) and nearly at its=20
maximum height. In fact, it's now rising a good=20
two hours before the first glimmer of dawn.

MARS, at magnitude +1.3, is basically lost in bright evening twilight.

JUPITER, at magnitude -2.5, shines in the south=20
to southwest during evening, the brightest star-like point in the sky.

SATURN, at magnitude +0.9, rises around 3 a.m.,=20
and glows in the southeast before and during=20
dawn, about 20=B0 to the upper right of brilliant=20
Venus. The best time to observe Saturn with a=20
telescope is during early dawn, when the planet=20
will be the least blurred by low-altitude=20
atmospheric turbulence. Saturn's rings have widened to 9=B0 or 10=B0 from=
 edge-on.
