Comet Pan‑STARRS Brightens to About Magnitude 4.5 in the Pre‑Dawn Sky

A brief pre‑dawn window favors Northern Hemisphere observers with clear eastern horizons.

Overview

  • Skywatchers can find the comet low before sunrise inside the Great Square of Pegasus near the star Algenib during a short viewing window.
  • The Comet OBServation database places its brightness near magnitude +4.5, which is close to the naked‑eye limit at very dark sites.
  • Most people will need binoculars, and a clear, unobstructed view of the eastern horizon will make the faint diffuse glow easier to spot.
  • Astrophotographers can frame the comet a few degrees from the edge‑on galaxy NGC 7814, creating a simple wide‑field pairing for long exposures.
  • The long‑period visitor was discovered by the Pan‑STARRS survey in September 2025 and it is due to pass the Sun this weekend and move south for better evening views in late April.
