Comet PanSTARRS to Shine in Predawn Sky Before It Vanishes
TL;DR
Comet C/2025 R3 PanSTARRS should reach naked-eye visibility (magnitude ~4.7) in the eastern predawn sky on April 17, about 90 minutes before sunrise, low on the horizon and a few degrees above Algenib in Pegasus. Locate the Great Square and spot PanSTARRS about five degrees above the star; binoculars (10x50) can reveal its glowing nucleus. The comet will brighten toward its perihelion around April 19, then move southward and fade from Northern Hemisphere skies for the foreseeable future.
