Umbral contact times are derived from NASA’s time of greatest eclipse and phase durations (partial —); they are accurate to about a minute. Moon altitude assumes the Moon sits opposite the Sun, which is true to within about a degree during an eclipse.
How to watch
- No special equipment or glasses needed: a lunar eclipse is safe to look at.
- Binoculars show the colour gradient across the shadow edge beautifully.
- Leave the city lights if you can: the dimmer the sky, the richer the red.
