Welcome to this issue of Qué tal. Here you will find useful observing information
about the visible planets, our Moon and other
moons, the Sun, as well as various 'things' celestial.
these web pages you will find monthly star maps for either the northern
or southern hemisphere that are suitable for printout. Animated
images are utilized to illustrate celestial motions such as orbital
motions of the planets, and other solar orbiting objects, or apparent
and real motions along the ecliptic and the local horizon. Regular
features include plotting the monthly positions of the visible planets
using heliocentric coordinates; following moon phases; conjunctions; the sun's
apparent motion and the Earth's real motion along the ecliptic.

At A Glance:Welcome to this issue of Qué tal.
This month the planets that are visible above the horizon shift in and out of view with Mercury moving east toward the Sun and
superior conjunction at the end of the month. Venus is setting lower each evening but remains visible over the western horizon at sunset. Look for Mars and saturn to be
above the eastern horizon at sunrise. Jupiter is nearing opposition next month and so Jupiter is visible nearly all night.
The highlight for December may be the departure of Comet ISON. If it survives perihelion the comet may be visible during the last few weeks
of the month as it moves from the northwest horizon toward the North Star by the middle of January. How long it will remain visible to the naked-eye is dependent on
many factors with the most significant the darkness of your skies.
