The Sky This Month - December 2021

Comet Leonard And The Geminids

If predictions hold, Comet C/2021 A1 (Leonard) should be a great target to view and image this month. It was discovered on January 3, 2021, by Gregory Leonard. The comet will be located close to the globular cluster M3 low in the east in the early morning hours of December 3. The fast-moving comet will be closest to the earth on December 13 at a distance of 34 million kilometres. Comet Leonard will be positioned south of the planet Venus low in the southwest on December 18. This will make a great photo op.

Here Comes The Lunar Eclipse

Nothing is more magical than viewing a lunar eclipse. A few times each year, the full moon steps into the earth’s shadow for a few hours, leaving us with lasting memories. Such an eclipse will take place on the night of Nov 18/19 with the Full Beaver Moon. This one will be extra special and appear very close to a total eclipse. Because of the geometry, the moon will be in the larger shadow of the earth except for a mere three percent, leaving the edge in sunlight. A lunar eclipse is very safe to enjoy.

Helen Sawyer Hogg (1905–1993)

On July 31, 1935, Helen Sawyer Hogg captured an image of Messier 14, an ancient globular cluster of about 150,000 stars, 30,000 light years from earth. She was one of the first female astronomers to directly operate a major research telescope. Her scientific research, professional leadership, and public outreach helped advance the study of astronomy in the 20th century.

Gas Giants and The Perseids

One of the best meteor showers is now underway. The Perseids runs from July 17 to August 24. According to Ottawa Centre’s Pierre Martin, “the peak of the Perseids producing about 90 meteors per hour will occur late afternoon on the 12th. Therefore the nights of Aug 11/12, as well as the 12/13, should reward you with 50 to 60 or more meteors per hour striking the atmosphere at 59 km/sec”. Pierre also says “a higher number of bright fireballs may be seen on nights before the peak rather than nights after”. Moonlight will not be a factor this year with the new moon on August 8. By contrast, next year’s Perseids takes place under a full moon, drastically reducing the hourly rate. This year's full Sturgeon Moon takes place on August 22.

The Sky This Month - June 2021

Sunrise Solar Eclipse

As mentioned last month, the long-awaited annular solar eclipse will occur on the morning of June 10th. Although most of the eastern part of Canada failed to enjoy the May 26 lunar eclipse, this area will see the sun covered by the moon as it rises behind trees, buildings and hills, making for some spectacular photo opportunities. An annular eclipse occurs when the moon is farthest in its elliptical orbit around the earth and covers about 99% of the sun called the “ring of fire”. For those living on the eclipse path, the one per cent of sunlight around the edge is still extremely dangerous to look at directly without proper filtration. This is not to be confused with a total solar eclipse where the closer moon blocks the entire sun from a few seconds to a few minutes depending on the moon’s distance in its orbit.

One Eclipse Leads To Another

This year the earth will witness four eclipses, two lunar and two solar. Depending on where you live in Canada, you will have a chance to see one of each or even both. On May 26 the Full Flower Moon will be subject to a total lunar eclipse. This is the largest moon of the year producing large tides.
