Comet Lemmon to Grace indonesian Skies October 25, 2025
Comet Lemmon will reach its closest approach to Earth-known as perigee-on october 20, 2025, but optimal viewing from Indonesia is anticipated towards the end of the month, peaking around October 25, 2025, and lasting for a few days thereafter.
The comet is expected to be visible low on the northwest horizon after sunset, potentially appearing in front of the constellation Serpens around October 29, 2025, according to The Sky Live. Observation time in Indonesia is best around 18:30 local time, or promptly following Maghrib prayer, looking towards the western horizon.
While potentially visible to the naked eye in exceptionally dark locations, a magnitude of 2.5-4.5 suggests optical aids like binoculars (7×50 or higher) or a small telescope will considerably enhance viewing. Observers may note a distinctive greenish hue to the comet’s head, caused by dicarbon molecules.
To maximize viewing opportunities, experts recommend: selecting a dark location away from city light pollution; utilizing optical aids; observing 30-60 minutes after sunset; and employing astronomy apps like Stellarium or KStars to track the comet’s position.
Lemmon’s Comet is a non-periodic comet, meaning it only enters the inner solar system approximately once every thousand years. Space UK notes this offers a unique viewing opportunity, as newly discovered comets rarely achieve a brightness easily observable from Earth. the comet’s prominent greenish coma, a result of sunlight interacting with dicarbon molecules, adds to its visual appeal.
