August 2022 Astronomy

Watch out for the Perseids Meteor Shower - Aug 12 & 13th, 2022

Saturn will lead the bright full Moon across the sky on the night of the Perseid meteor shower. The meteor shower peaks on August 12/13 but they can be seen for a week or two on each side of the maximum night to avoid the full light of the Moon.

Following two hours behind the Moon is Jupiter. If you hold binoculars very steady, you may be able to see the Galilean moons as they slowly orbit the planet. Watch them shift position from night to night.

Main Meteor Showers

Meteor showers are best observed after midnight when our hemisphere is ploughing into the meteor stream. Although the duration of the most active portion of the shower is short, some shower meteors can be seen many days on either side of maximum.

There are about a dozen significant meteor showers each year. This is a list of only the three major ones that have different “characters”.

The Quadrantids radiate from an area 20-degrees east of the Big Dipper’s handle. The short duration for the shower is somewhat balanced by the possible bright “fire balls” that are produced. And, the just-after full Moon on January 3/4 that will reduce the visibility of the fainter meteors and makes this an unfavourable year for the shower.

The Perseids are the premier shower of the year. Its long duration will bridge cloudy nights. However, the near full Moon on August 12 makes this a poor year to observe this shower.

Planetary Configurations

When at Opposition, planets will appear on the opposite side of the sky from the Sun – very roughly on the meridian at midnight. Conjunctions are when the planet has the same “longitude” as the Sun. A Superior Conjunction is when the planet is on the  other side of the Sun, and an Inferior Conjunction is when it is between the Earth and the Sun. Only Mercury and Venus can be  at Inferior Conjunction. Maximum elongation is when Mercury and Venus appear farthest from the Sun in our sky. This occurs  either in our morning eastern sky (mor.) or our western evening sky (eve.). Do not apply the Ottawa-correction times to the times in this table.
