Rare Comet Tsuchinshan-ATLAS Visible to Naked Eye After 80,000 Years: How to Spot It This Week
After months of anticipation, astronomers and skywatchers around the world are gearing up to witness a rare celestial event – the sighting of Comet Tsuchinshan-ATLAS. This comet, formally known as C/2023 A3, is expected to be visible to the naked eye in the predawn sky starting this week. With an estimated 80,000-year-long orbit, this comet’s appearance is truly a once-in-a-lifetime opportunity for many.
Anticipation Builds as Comet Approaches Perihelion
Comet C/2023 A3 is set to reach perihelion, its closest point to the sun, on Friday, Sept. 27. This key event is expected to coincide with the comet’s peak brightness, making it easier for observers to spot in the sky. Skywatchers in the Northern Hemisphere will have the best chance of catching a glimpse of the comet above the east-southeast horizon about 30 minutes before sunrise between Sept. 27 and Oct. 2.
For those looking to maximize their viewing experience, the mornings of Sunday, Sept. 29 and Monday, Sept. 30 are likely to be the ideal times to observe the comet. During this period, C/2023 A3 will be accompanied by a delicate waning crescent moon, adding a beautiful celestial backdrop to the spectacle.
Preparing for the Comet’s Appearance
While there is hope that Comet C/2023 A3 will be visible to the naked eye, the unpredictability of comets means that it’s wise to have a good pair of stargazing binoculars or a small telescope on hand to enhance the viewing experience. The comet’s dusty tail, formed as a result of dust and ice melting as it approaches the sun, should be visible to observers, offering a unique and awe-inspiring sight in the night sky.
The brightness of the comet remains a mystery, with some astronomers speculating that it could rival the 20 brightest stars in the night sky. This uncertainty only adds to the anticipation and excitement surrounding this rare celestial event.
Future Viewing Opportunities and Conclusion
After Oct. 2, Comet C/2023 A3 will disappear into the glare of the sun, only to reemerge in the night sky of the Northern Hemisphere around Oct. 12. For those in midnorthern latitudes, the comet will be positioned close to the western horizon, providing another opportunity to witness its beauty before it gradually fades from view.
As we prepare to witness Comet Tsuchinshan-ATLAS make its appearance after 80,000 years, astronomers and skywatchers alike are eagerly anticipating the opportunity to observe this rare celestial event. With careful planning and a bit of luck, those who venture out in the early morning hours this week may be rewarded with a once-in-a-lifetime view of this extraordinary comet.
