July 4 – Mercury is at its western maximum equinox

Mercury will reach its maximum western ecliptic, 21.6 degrees from the sun. This is the best time to observe Mercury as it will be highest above the horizon in the morning. Look for this planet in the eastern sky before dawn!

July 10 – New Moon

The Moon will be on the same side as the Earth and the Sun, so we won’t see the Moon in the night sky. This phase will take place at 8:17 p.m. This is the best time of the month to observe faint objects such as galaxies, star clusters, etc. for then these objects are not obscured by moonlight.

July 24 – Full Moon

The Moon will vibrate against the Sun and the entire surface facing the Earth will be illuminated. This phase will take place at 9:37 p.m. This full moon is known to Native Americans as the Deer Moon because at this time of year the deer change their antlers. This moon is also known as Thunder Moon or Grass Moon.

July 28 and 29 – Delta Aquarids Meteor Shower

The Delta Aquarids meteor shower is a moderate meteor shower and at its peak, up to 20 meteors appear per hour. The Delta Aquarids meteor shower is formed from debris from comets Marsden and Kracht.

This meteor shower occurs annually from July 12 to August 23 and peaks on the night of July 28 and early morning of July 29. The waning moon will cover many faint meteors. But if you are patient enough, you will still have the chance to see bright shooting stars. It is best to observe in dark places after midnight. Meteor trails tend to originate from the constellation Aquarius (Aquarius), but can appear anywhere in the sky.
