Chasing Pan-STARRS: dawn views of a 170,000-year comet
Space.com writer Jamie Carter explains that the rare long-period comet C/2025 R3 (Pan-STARRS) returns after ~170,000 years and will brighten toward around magnitude +3 as it nears perihelion in April; Northern Hemisphere observers should aim about 90 minutes before sunrise between April 10–20, near the Great Square of Pegasus, using binoculars and a telephoto camera for best sightings and photos, while Southern Hemisphere observers get later opportunities; the viewing window is tight because increasing daylight and the sun's glare will wash it out, making this a fleeting dawn hunt for a relic from the solar system's edge.
