If you’re looking for something unforgettable to do on warm summer nights, three major meteor showers are set to light up the skies over Ontario in the coming months. From dazzling fireballs to subtle streaks at dawn, skywatchers of all experience levels may want to mark their calendars.

Arietids (May 29 – June 17)

One of the strongest daytime meteor showers of the year, the Arietids peak around June 7 and are best viewed during the dark hour before dawn.

According to EarthSky, meteoroids from this shower strike Earth’s atmosphere at speeds of 39 km/s (87,000 mph). While the exact origin remains uncertain, spaceweather.com reports they may come from sungrazing asteroid 1566 Icarus, Comet 96P/Machholz, or the Kreutz family of comets.

Although the shower can produce up to 200 meteors per hour, much of that activity occurs during daylight, making most meteors difficult to spot. A first-quarter moon on June 3 will provide better conditions for early morning viewing.

Delta Aquariids (July 18 – August 21)

The Delta Aquariids are known for their steady, consistent activity and originate from Comet 96P/Machholz. According to EarthSky, the shower peaks around July 30, with the best viewing from late evening into the early hours of the morning.

Observers under dark skies can expect to see about 15 to 20 meteors per hour. A first-quarter moon on August 2 will help limit light interference during peak nights.

Perseids (July 14 – September 1)

Arguably the most popular meteor shower of the year, the Perseids are famous for their fast, bright meteors and occasional fireballs. The shower originates from Comet Swift-Tuttle and is set to peak in the afternoon of August 12, with the best viewing before dawn on August 11 and 12.

According to EarthSky, this year’s show will compete with a waning gibbous moon, which will be nearly full on August 9. While moonlight may wash out some of the dimmer meteors, up to 90 meteors per hour could still be visible under favourable conditions.

If you’re planning to watch one or all of these showers, Space.com recommends the following:

• Red flashlight — Fainter meteors require eyes to adjust to the dark, especially when you’re using a night-sky map. The red light will help preserve your night vision.
• Warm clothing — It can get pretty chilly as you wait for the meteor showers. Grab a warm hat, coat, a scarf and a sleeping bag, if staying outdoors for a long period of time.
• Hot drink — A hot beverage will help keep you warm. Tea and coffee are often the go to choice as it also helps you stay awake.
• Deck chair — Looking up for hours at a time could put a strain on your neck. It’s advised to use a deck chair that will keep you in an inclined position for maximum comfort.
