These sky maps show the bright stars and the planets which are visible from the northern hemisphere, looking South and North, on the 15th of July 2013 (at 23h). The vertical line is the projection onto the sky of the local meridian. The red circular arc on the Southern horizon is the ecliptic (the apparent path of the Sun during the year).

During its apparent motion along the ecliptic, the Sun is accompanied by several close planets. Those which are to the East are observable at sunset or at the beginning of the night, depending on their elongation, while those which are to the West will be observable at the end of the night or at sunrise, again depending on their elongation. The following figure shows the configuration for the 15th of July 2013.
