Monthly Start Chart

July evening skies over Hawai‘i

July 2021

Venus, at mag. -3.9, shines low in the west after sunset in the constellation Cancer. Look for nearby Mars, red and much dimmer at mag. 1.8. On the 8th in the predawn sky, look for 0.1 mag Mercury next to the nearby crescent Moon. After midnight is a good time to view Jupiter (mag.  -2.7) and Saturn (mag. 0.1), climbing high into the sky in the southwest.

Making Your Own Star Charts


This star chart is produced using the Cartes du Ciel Sky Charts program written by Patrick Chevalley.

This free program runs on Windows and Macintosh computers. If you are interested in making your own star charts for use at home or school, you may obtain a copy of the program and its documentation from this website.

This program is very powerful and can be used to generate star charts far more detailed than the one provided here.
