Monthly Star Chart

April evening skies over Hawai‘i

April 2022

Mercury is at its greatest elongation on the 29th at 21 degrees from the Sun. Look for it in the west after sunset at magnitude -1.2. Venus rises several hours before dawn shining brightly in the east. By the end of the month, Jupiter, Mars, Venus and Saturn are in conjunction in the predawn sky. Jupiter is mag. -2.1, Saturn magnitude 0.7 and nearby Mars is mag. 1.1. Comet C/2021 O3 (PanSTARRS) reaches perihelion on the 21st and peak brightness the 23rd-24th. The Lyrid meteor shower peaks on April 21-22 but pre-dawn on the 23rd is likely to be the best viewing given the moonlight.

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.
