Moon-gazers are in for a treat this week as the moon puts on a show in the night sky. Instead of waiting for a full moon, astronomy enthusiasts are advised to look out for the delicate crescent moon, which offers a more pleasing sight according to experts. This week, viewers will have the opportunity to witness the moon waning to a slender crescent in the predawn hours before reappearing in the post-sunset sky.
Not only is the moon a stunning sight, but it is also moving towards a specific position in its orbit that will cause something extra special next month. On October 14, an annular solar eclipse will be visible from nine U.S. states, while the rest of the Americas will experience a partial solar eclipse.
To make the most of this week’s moon sightings, here’s what you need to know:
On Monday, September 11, early risers can catch a glimpse of a 12%-lit waning crescent moon located just 3 degrees from the Beehive Cluster (M44) in the east. With a pair of binoculars, viewers can also spot a super-bright Venus in the same vicinity.
On Tuesday, September 12, an even slimmer crescent moon, just 6%-lit, will appear in the east-northeast before sunrise. This moon will display “Earthshine,” which is sunlight reflected by Earth onto the lunar surface. Venus will also be in close proximity to the moon.
Wednesday, September 13, offers another opportunity for moon-gazers to observe a super-slim 2.4%-lit crescent moon in the east-northeast. However, due to the gathering dawn, a cloud-free horizon is necessary to see it. Using binoculars can increase the chances of spotting it.
Friday, September 15, marks the New Moon phase, when the moon is lost in the glare of the sun. Although it won’t cause a solar eclipse this month, in 29 days, the moon’s path will cross the ecliptic, resulting in a “ring fire” annular solar eclipse visible from eight U.S. states, Central, and South America.
Finally, on Sunday, September 17, an evening view of the crescent moon will be visible in the west-southwest just after sunset. With only 8% illumination, the bright star Spica will be visible just below the moon. However, binoculars may be required, as Mars will likely be too low to see.
In addition to moon-gazing, viewers can also enjoy the Summer Triangle, consisting of Deneb in Cygnus, Vega in Lyra, and Altair in Aquila. This week, the Summer Triangle will be seen inching towards the western sky.
For a more immersive experience, experts recommend using binoculars to reveal a second layer of the night sky, particularly star clusters just beyond human eyesight.
Remember to consult online planetariums for the most accurate location-specific information on celestial events. Clear skies and happy stargazing!
