A new comet, Comet C/2025 A6 Lemmon, was recently discovered by astronomer David C. Fuls on Jan. 3 through the Mount Lemmon survey program. This comet, which passed closest to Earth on Tuesday, is now more visible in the sky and is currently at its peak visibility. According to Robert Massey from the Royal Astronomical Society, this is the best time to observe Comet Lemmon, as it won’t return for another 1,300 years.
To spot the comet, look towards the western sky after sunset. Use the Big Dipper as a reference point – the first star in the handle of the constellation points to the bright star Arcturus in the Boötes constellation, above which Comet Lemmon can be seen. While amateur astronomers have captured stunning images of the comet, it will appear as a fuzzy object in the sky to the naked eye.
Despite being brighter now and visible to the naked eye in darker areas, using binoculars can enhance the viewing experience, especially in urban locations. For optimal viewing, Friday is recommended as the moon will be minimally illuminated, gradually increasing brightness as it approaches the first quarter by Monday. Comet Lemmon will be observable in the Northern Hemisphere until mid-November, gradually descending in the southwestern sky after Sunday.
To locate Comet Lemmon accurately, consider using astronomy apps such as SkySafari and Stellarium. Take advantage of this rare opportunity to witness the comet before it diminishes in visibility.
