Sky Watch for June 2021

June Bright Planets

Venus, Mars, Jupiter, and Saturn all grace the night sky this month. Here are some of the best sky-watching dates to mark on your calendar.

  • June 1: If you’re a night owl, watch the Moon meet bright Jupiter tonight. First, look low toward the southeast for the waning gibbous Moon. Glowing right above (6 degrees to its upper left) is brilliant Jupiter (magnitude -2.4). Jupiter will still be up as dawn begins.
  • June 11: In evening twilight, 40 minutes after sunset, bright Venus now stands 8 degrees up in the western sky—not high, but a marked improvement from last month. It will float to the left of the thin crescent Moon on the 11th, while the dark of the Moon glows brightly with earthshine. See Venus’s setting time.
  • June 13: Just as astronomical twilight gives way to nightfall, look for planet Mars, which shines higher up in the western sky. It’s now fairly dim at magnitude 1.8. A good time to spot Mars is on the 13th. Look first for the crescent Moon; Mars dangles right beneath the crescent’s point. See Mar’s setting time.
  • June 27: Giant Saturn and Jupiter now rise just before midnight, so you no longer need alarms for predawn viewing. About 11:30 p.m. local time, look for the waning gibbous Moon in the southeast sky as it hovers right below yellowish Saturn.
  • June 28 and 29: Catch the waxing gibbous Moon sweep below brilliant Jupiter on the 28th and 29th. Look low towards the southeast at 11:30 p.m. local time.


Sunrise Eclipse of the Sun on June 10

June 10 brings an “annular solar eclipse” in southern Ontario, Canada, at at 5:49 A.M. Eastern Time. The Moon covers all of the Sun’s disk except the outer rim, creating a dramatic “ring of fire” (See photo at the top of the page.) Not many folks are in the path of annular solarity; the best place to view this eclipse is off the coast of Lake Superior northeast of Thunder Bay western shore of Lake Nipigon. 

Millions more people in eastern U.S. and Canada will see a dramatic “partial solar eclipse” at sunrise (about 5:30 A.M.). Check your sunrise times. For example, those in NYC will see a whopping 80% eclipse. Folks in Philadelphia, Atlantic City, Boston, Montreal, Ottawa, and Toronto will also witness a deep partial eclipse. What you see depends on where you live. If you’re on the Altantic ocean with a few across the water, you may see a crescent-shape Sun rising from the waves!  If you live further West, it may look like the Moon took a bit out of the Sun! See the map below for more details.

Summer Solstice on June 20

The solstice brings summer to the Northern Hemisphere on the 20th at 11:32 p.m. EDT. On the solstice, the Northern Hemisphere enjoys the longest daylight hours of the year. See all about the summer solstice.

Full Moon for June 24

Thursday, June 24, brings the full Moon at 2:40 P.M. EDT (18:40 GMT), rising in the east as the Sun is setting, and setting in the west at sunrise. Find out why June’s full Moon is called the Strawberry Moon and get viewing tips on the June Full Moon page.
