Get ready for a celestial treat this Wednesday, November 12th! We're about to witness a unique alignment of planets and stars that will leave you in awe. But here's where it gets controversial... some might argue that the timing is a bit tricky, so pay close attention!
On this particular evening, you have a chance to spot Mercury and Mars, alongside the stunning red giant Antares. These celestial bodies will be visible in the southwestern sky, just after sunset. It's a brief window of opportunity, so make sure you're quick!
The Celestial Dance
Let's break it down. On November 11th and 12th, skywatchers will be treated to a series of fascinating events. Jupiter's moons, Io and Europa, will transit across the gas giant's disk, accompanied by their shadows. This celestial dance will be visible to observers in the Eastern time zone, with precise timings provided.
Mars and Mercury's Close Encounter
During the afternoon of November 11th, Mars and Mercury will have a close angular separation of 1.3 degrees north of each other. This event is best observed using binoculars in the twilight conditions shortly after sunset. Antares, the red giant, will serve as your navigational guide.
Lunar Occultation and Telescopic Treats
In the early morning hours of November 12th, the waning crescent Moon, illuminated at 38-40%, will be positioned between Regulus and Denebola in the constellation Leo. This offers a detailed telescopic view of craters Copernicus and Kepler near the western terminator. Additionally, certain regions, including northern Canada and Alaska, will witness a lunar occultation of the 4th-magnitude star Rho (ρ) Leonis.
A Step-by-Step Guide
To locate Mercury and Mars, follow these steps:
- Look for Antares, which shines at magnitude 1.1, about 5 degrees to the left of Mercury. Use Antares as your starting point.
- Begin your search for Antares low in the southwest, approximately 25 minutes after sunset. It will be only 3 degrees above the horizon.
- Center Antares in your binoculars and sweep to the right to find Mercury.
- From Mercury's position, move slowly 1.3 degrees in the direction of one o'clock. This should lead you to Mars.
- Remember, you have a short window of about 10 minutes to locate Mars, as the region quickly sets into the hazy air near the bright horizon.
Sunrise, Sunset, and Moon Phases
Sunrise: 6:42 A.M.
Sunset: 4:46 P.M.
Moonrise: N/A
Moonset: 1:20 P.M.
Moon Phase: Waning Crescent (40%)
The Moon's Journey
The Moon will rise to the lower left (east) of Regulus in Leo shortly after midnight. By 5 A.M. local time, it will have reached a height of 50 degrees in the southeast. The Moon appears nestled between Leo's two brightest stars, Regulus (the Lion's heart) and Denebola (the Lion's tail).
As a 38-percent-lit crescent, the Moon showcases its western limb, while the rest of the lunar nearside is darkened by sunset. Just beyond the terminator dividing night and day, you'll find the well-defined crater Copernicus in the lunar northwest. With a diameter of 56 miles (90 kilometers), Copernicus' eastern rim will appear brighter than its western side due to the setting Sun illuminating it from the west. The bright rays of ejecta surrounding the crater are now muted but still visible through a telescope.
To the southeast of Copernicus lies the smaller Kepler, with a width of about 20 miles (32 km). Its rays should be slightly more visible, overlapping with those of Copernicus in the region between the two craters.
A Note for Northern Observers
If you're located in northern Canada or Alaska, you're in for a special treat! You'll have the opportunity to witness the Moon occult the 4th-magnitude star Rho (ρ) Leonis. For more details, check out the International Occultation Timing Association's webpage.
So, are you ready to embark on this celestial adventure? Don't miss out on this unique opportunity to witness the beauty of our universe. Happy stargazing, and may the skies be ever in your favor!
