Bandar Seri Begawan – Keep an eye out for Comet 12P/Pons-Brooks, it may brighten to naked eye visibility as it arrives perihelion in April.

Comet Pons Brooks will be at its closest distance of 116.8 million km to the Sun on Sunday, April 21 2024. It thus reached its maximum brightness of magnitude 4.2, expected visible to the unaided eye.
Comets are so unpredictable for sudden flare-ups in brightness, so you might get a chance to catch sight for this spectacular show.

From Brunei Darussalam, the comet will set in the west-northwest, hovering about 10 degrees above the horizon in the evening twilight all through April.

Like other comets, 12P/Pons-Brooks is made of a mixture of ice and rocky materials. As it approaches the Sun, these volatile matters transform to gas and dust which cause an expansive cloud (coma) and a distinctive tail.

By the end of April, it then fades very rapidly and moves back out into space. Comet Pons-Brooks will take another 71 years for it to complete another full journey around the sun – a once in a lifetime experience to see the cosmic wanderer!

It is now viewable over in the west horizon in the evening twilight from Brunei Darussalam and will reach as bright as a stellar magnitude 4.0 which is within naked eye limit.

The extraterrestrial object should appear as a fuzzy green blob with a hazy tail as viewed from a small telescope or binoculars.

Wait for darkness (after 7.15 pm), it is a simple cosmic target to be photographed – Get out your tripod, attach a medium lens and point the camera towards the west horizon.

From the northern hemisphere, comet 12P will remain viewable for the next 1 or 2 weeks before disappearing into the bright sun’s glare and proceeding into the southern sky.

Comet 12P/Pons-Brooks is nicknamed as β€œdevil comet” for its unusual pointy shape. Just a week before its closest approach to the Sun (perihelion), The comet was photographed last night, April 14, 2024, from Tutong, which evidently displayed two distinct β€œhorns” of gas and ice.

Comet 12P is a Halley-type periodic comet with an orbital period of about 71.3 years. In 2024, the icy wanderer is speeding through the inner solar system and expected to reach its maximum brightness, potentially becoming visible to the naked eye during the perihelion.

However, bright twilight and moonlight may wash out the comet’s brilliance, so skywatchers may need binoculars or telescopes to catch a glimpse.
