Blue moon tonight will be the last super blue moon until 2037 — here are 5 critical details you can’t miss
- Visible in amazing clarity: Tonight’s blue moon is also a supermoon, meaning it will appear up to 14% larger and 30% brighter than a typical full moon, making it a jaw-dropping sight even in light-polluted cities.
- Rare timing: This is the second full moon in August, which qualifies as a “blue moon” under the seasonal definition—an event that won’t repeat until 2037, so this is your only chance for years.
- Best viewing window: Look east just after sunset for the most dramatic effect as the moon rises low on the horizon; known as the “moon illusion,” it will seem especially huge and orange.
- No actual blue color: Despite the name, the moon won’t turn blue—unless you’re near volcanic ash or heavy wildfire smoke that can tint the light; pack binoculars or a telescope for craters and seas.
- Social media gold: Use the hashtag #BlueMoonTonight to join millions sharing photos worldwide; NASA will host a live stream at 8 PM ET for clouded-out viewers, so you won’t miss the moment.
