Tonight's lunar eclipse is unusually deep. It is still partial, not total.
Most of the Moon will enter Earth's dark inner shadow overnight, with visibility spanning the Americas, Europe, Africa and western Asia.

How deep
NASA lists an umbral magnitude near 0.93, meaning about 93% of the Moon's diameter enters the umbra. A thin portion remains outside, so totality never begins.
Where to look
The eclipse is visible across much of the Americas, Europe and Africa. Exact local timing and how much is visible depend on moonrise, moonset and weather.
Why it may redden
Earth blocks direct sunlight, while light filtered through the atmosphere can tint the shadowed Moon red or orange. No solar-eclipse glasses are needed.
