   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 visible planets, those above the horizon and bright enough to be seen with the naked eye, are split between the morning and evening skies. Over the eastern and southeastern horizons before sunrise are Mercury and Saturn. Jupiter rises before midnight and so it is visible in the morning skies but over the western horizon at sunrise. In the evening look west for bright Venus and less bright (in magnitude!) the planet Mars. This is also the start of the current eclipse year and there is a penumbral lunar eclipse on the 11th and an annular solar eclipse on the 26th.
   The closest Dwarf Planet, Ceres, sets several hours after sunset local time and interestingly is in the same viewing direction as another Dwarf Planet, Eris, and the outer planet Uranus.
