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.
During September the visible planets are all visible either as evening or morning planets. Jupiter and Venus rise in that order
before the Sun rises, while Mercury, Saturn, and Mars all set in that order after sunset. Depending on your location you will be able to
see the Moon either pass by closely or pass in front of several planets and asteroids. September is also the month when northern hemisphere summer
changes to autumn while it is the opposite in the southern hemisphere.
