The Moon is fully immersed in Earth's umbral shadow — a Blood Moon occurs. Magnitude 1.1392 means deep totality with vivid red coloring.

🌍 Where to See This Eclipse

🌕 Lunar Eclipse Visibility

🌍 South America 🌍 Oceania 🌍 Africa 🌍 Antarctica 🌍 Asia

Visible from the night side of Earth — approximately half the world can observe this lunar eclipse. The eclipse is visible wherever the Moon is above the horizon during the event.

👁️ What to Expect

Observing the Total Lunar

🔴During totality, the Moon turns deep red — the "Blood Moon" effect. This is caused by Earth's atmosphere refracting red sunlight onto the Moon.
👁️No special equipment needed! A lunar eclipse is safe to view with the naked eye. Binoculars enhance the experience.
📸Photography tip: expose for the Moon's detail — try ISO 800, f/8, 1/60s during partial phases; ISO 1600, f/5.6, 2s during totality.
