Muscat: On Tuesday, skywatchers in Oman were treated to a rare spectacle as Comet A3, also known as Comet Tsuchinshan-ATLAS (C/2023 A3), streaked across the clear desert sky. This marked one of the most anticipated sightings of the year, as the comet, discovered in 2023, has gained brightness over recent months.
The comet's appearance comes as part of its journey through the inner solar system. It is currently speeding toward its closest approach to the Sun, an event known as perihelion, which occurred on September 27. After perihelion, the comet becomes more visible in regions closer to the equator, making Oman a prime location for observation. Stargazers in the region are encouraged to look eastward shortly before sunrise.
Comet A3 is expected to be visible until mid-October when it reaches its closest approach to Earth. After October 10, it will reappear in the evening sky, making it easier to spot without the interference of sunrise. However, binoculars or a telescope are recommended for those hoping to get a closer look at the comet’s tail and glowing nucleus, as it may not be easily visible to the naked eye due to light pollution in urban areas.
This comet has been spotted globally, from Puerto Rico to Australia, thrilling astronomers and enthusiasts alike. While its brightness has varied, Comet A3 continues to capture attention and may remain one of the brightest comets of the year if it survives its close encounter with the Sun.
Omanis will have more opportunities to witness this cosmic traveller in the coming days, with the best views expected just after sunset as it moves westward.
