On April 25, 2026, skywatchers in parts of the eastern United States will witness a rare celestial event: the bright star Regulus in the constellation Leo will disappear behind the Moon for up to an hour in a phenomenon known as an occultation. This dramatic alignment offers a chance to see the star blink out suddenly and then reappear, a vivid demonstration of the Moon’s motion across the sky.
🌌 What’s Happening?
- Event: Lunar occultation of Regulus, Leo’s brightest star.
- Date: Saturday, April 25, 2026.
- Duration: Up to one hour depending on location.
- Cause: The Moon’s orbit carries it directly in front of Regulus, temporarily blocking it from view.
🔭 How to Watch
Visibility Zone:
- Best seen from the Mid-Atlantic and Southeastern U.S.
- Locations south of a line from Michigan → Ontario → New York → Pennsylvania → New Jersey will see the star vanish behind the Moon.
- North of this line, observers will see a near miss.
Disappearance: Regulus will vanish behind the Moon’s dark limb, making the effect sudden and striking.
Reappearance: The star will re-emerge from the Moon’s sunlit edge, best viewed with a telescope due to glare.

🌠 Tips for Observers
- Binoculars or telescope recommended for best view.
- Block the Moon’s glare with a tree limb or building edge to spot Regulus with the naked eye.
- In New Jersey, observers along the “graze line” may see Regulus blink on and off multiple times as the star skims the Moon’s rugged terrain.
✨ Why It Matters
Occultations are rare opportunities to witness the precision of celestial mechanics. Watching Regulus disappear and reappear highlights the Moon’s orbital motion and the delicate geometry of the night sky.
