December 2017
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.
Among
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.
For additional observing information and other useful Earth and Space news
posted several times each week follow my WordPress Blog at bobs-spaces.
At A Glance: Welcome to this issue of Qué tal.
This month Mercury becomes the last evening planet for a while as it
moves into superior conjunction and reappears in the morning skies toward the end of the month.
Venus may be seen for a while in the morning skies but soon Venus moves into superior conjunction - early next month.
Mars and Jupiter both are visible above the southern horizon before sunrise local time.
Saturn is too close to the Sun and moves into solar conjunction toward the end of the month.
