Observers will have multiple opportunities to see the moon at its brightest on Thursday, even if the weather is less than ideal. The full moon will be visible on the horizon Thursday evening, offering a spectacular view as it rises. If conditions remain cloudy, skywatchers can try again Friday night.
Some lucky viewers might also spot a rare moonbow — a lunar rainbow created when moonlight refracts through water droplets in the atmosphere. These occur only when the full moon is relatively low in the sky, making early evening and late-night hours the best time for potential sightings.
The worm moon is a name that originated in Native American, Colonial American, and European traditions.
