Rare Celestial Object Sighting Over Bengaluru | Opportunity to view Comet C/2023 A3 in naked eye

Introduction:

Over the past few days, the skies over Bengaluru have been graced by a rare celestial event: the appearance of Comet C/2023 A3 (Tsuchinshan–ATLAS). This non-periodic comet has sparked excitement among astronomy enthusiasts and casual observers alike.

Discovery of Comet C/2023 A3 (Tsuchinshan–ATLAS):

Comet C/2023 A3 was first discovered by the Purple Mountain Observatory in China on January 9, 2023. A month later, it was independently observed by the Asteroid Terrestrial-impact Last Alert System (ATLAS) in South Africa, which contributed to its official naming. 

This comet is classified as non-periodic, meaning it rarely passes through our solar system. According to Bengaluru-based astrophysicist R.C. Kapoor, these types of comets are considered "outsiders" to our solar system due to their unique trajectories.

The Comet's Journey and Recent Appearance:

The comet passed its perihelion, the closest point to the Sun, on the night of September 27/28, at a distance of 56 million kilometers from the Sun. 

For residents of Bengaluru, the comet has been a visible spectacle during the early morning hours over the past few days and is expected to remain observable in the morning skies for the first few days of October. 

Capturing the Moment: Enthusiasts in Action:

Amateur photographers and astronomy lovers in Bengaluru have been quick to capture this rare event. One such enthusiast, Deepak Choudhary, managed to photograph the comet on September 28. 

After checking the skies at around 4:30 a.m., he set up his DSLR camera and tripod to photograph the comet between 5:00 a.m. and 5:30 a.m. “It was a thrilling experience to see Comet C/2023 A3 on my camera screen,” Mr. Choudhary said, noting that it might be one of the first times someone from India captured the comet so closely after its reappearance in the northern hemisphere.

Future Viewing Opportunities:

Although the comet has been primarily visible in the morning sky, this will change in the coming weeks. 

From October 12 onwards, the comet will shift to the western sky, becoming visible shortly after sunset. 

At this point, Comet C/2023 A3 will be at its closest approach to Earth, offering an opportunity to view it with the naked eye. 

This is expected to be one of the best viewing moments as the comet passes closest to our planet.

Understanding the Comet's Origins:

Prof. Kapoor explained that Comet C/2023 A3's orbit has an eccentricity slightly above one, indicating that it is an object from the Oort Cloud. 

The Oort Cloud is a distant, spherical reservoir of comets, located between 10,000 to 100,000 astronomical units (AU) from the Sun. 

Objects from this region have extremely long orbits, often taking thousands or even millions of years to complete a single trip around the Sun.

Conclusion:

The sighting of Comet C/2023 A3 (Tsuchinshan–ATLAS) over Bengaluru has captivated both the scientific community and the general public. 

With its rare appearance and origins in the distant Oort Cloud, the comet offers a glimpse into the farthest reaches of our solar system. 

For those who haven’t yet had the chance to see it, there’s still time to catch this extraordinary celestial event, either in the early morning or after sunset starting from October 12.
