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 the morning skies are still dominated by Venus shining brightly over the eastern horizon in the hours
before sunrise. However the other inner planet Mercury and Mars join Venus and the star Regulus in Leo the Lion for a series of conjunctions.
Both Jupiter and Saturn are visible over the south to western horizons at sunset local time.
