This week promises an exciting array of celestial events for skywatchers, including a bright comet, a solar eclipse, stunning auroras, and a temporary “mini moon.” Here’s a detailed guide to what you can expect in the night sky.
Comet A3: A Spectacular Sight
When to View: September 30 – October 2
Best Viewing Time: 75-60 minutes before sunrise
Location: Eastern horizon, Northern Hemisphere
Comet A3, also known as C/2023 A3 (Tsuchinshan-ATLAS), is becoming bright enough to be visible to the naked eye. Although it will reach its peak visibility around October 12, early risers can catch a glimpse of it in the coming days.
Viewing Schedule:
- September 30: Look east an hour before sunrise to spot Comet A3 near a 5%-lit waning crescent moon.
- October 1: Find Comet A3 on the right with a 1.5%-lit crescent moon on the left.
- October 2: Comet A3 will be alone in a dark sky, with the bright star Regulus above.
Annular Solar Eclipse: Ring of Fire
When: October 2
Where to See: Southern Hemisphere, including Easter Island, southern Chile, and Argentina
On October 2, a “ring of fire” annular solar eclipse will occur, where about 93% of the sun’s disk will be obscured by the moon. From the centerline, the eclipse will last approximately six minutes. Remember, you must use solar eclipse glasses to view this phenomenon safely.
Earth’s New Mini Moon
When: September 29 – November 25
Location: Eastern horizon, Northern Hemisphere
A temporary asteroid, designated 2024 PT5, will become a “mini moon” as it enters Earth’s orbit for 57 days, starting September 29. While it is only 11 meters in diameter, making it visible only through large telescopes, it represents a fascinating occurrence in our night sky.
Crescent Moon and Venus
When: October 5-6
Where to See: Western horizon after sunset
Take a break from early morning viewing as a crescent moon will be visible near the planet Venus. On October 5, a 6%-lit crescent moon will appear below and to the left of Venus. The following night, the crescent moon will move farther left, creating a beautiful celestial display.
Strong Auroras Expected
When: September – October 2024
Location: Northern sky
Around the equinox on September 22, scientists noted a potential increase in geomagnetic activity, which could lead to more intense auroras. The alignment of Earth’s magnetic fields with solar wind may cause stunning displays of the northern lights, making this a perfect time for aurora watchers.
Conclusion
This week is brimming with exciting celestial events for both amateur and seasoned astronomers. Be sure to mark your calendars and prepare for some breathtaking views of the night sky!
