Don't miss this comet right before sunrise!
Right now, people on every continent are waking up before dawn and pointing cameras at the same patch of sky. They are all looking for the same thing. Here is what they are finding.
Comet C/2025 R3 (PanSTARRS). This week. This is what the world is seeing.
The observations started slowly. On March 20, astronomer Alan Hale — one of the co-discoverers of Comet Hale-Bopp — became the first person to spot C/2025 R3 with the naked eye using binoculars. At that point, it was at magnitude 9. You needed a telescope to see it. That was 25 days ago.
By April 4, it had brightened to magnitude 6 — the very edge of naked-eye visibility under perfect conditions.
By April 8, observers were reporting something extraordinary: the ion tail had grown to at least 7 degrees in length. Seven degrees. That is 14 full Moons laid side by side across the sky. A gas tail driven straight away from the Sun by the solar wind, blue-white and razor-straight, stretching across more than a finger-width of sky at arm's length. Astrophotographers with Canon cameras and 200mm lenses were capturing it from their backyards in 15-second exposures.
By April 10, the comet was officially naked-eye accessible in dark skies. Multiple observers confirmed it independently. Photos began appearing on astronomy forums within hours — fuzzy green-cyan comets with trailing tails, soft against the black background.
On April 11, the first confirmed naked-eye sighting with no optical aid: magnitude 5.1, confirmed by independent observers. No binoculars. Just eyes. Just a dark field.
By April 13, the ion tail had extended to more than 10 degrees — equivalent to 20 full Moons laid end to end. The tail is now visible in binoculars as a distinct straight blue-white streak pointing away from the Sun. The dust tail — shorter, curved, ivory — is visible separately. Two tails, both visible.
Space skywatching columnist described it this week as actively hunting the comet before dawn, the comet low in the eastern sky at 90 minutes before sunrise. On April 14, a 12% illuminated waning Moon is nearby as a pointer.
The best is still ahead. Perihelion is April 19. The predicted brightness: magnitude 3. Equivalent to the brightest stars in the sky. The New Moon on April 17 gives the darkest possible sky during the peak.
Every morning this week, thousands of people are waking up before dawn to look. Some find it. Some do not. All of them are looking at the same place — a soft smudge above the northeastern horizon, moving slowly against the stars, growing slightly brighter each morning.
You could be one of them tomorrow.
