How the Moon covers the Sun
What you will notice
The Sun looks as if someone has taken a bite out of it. Without eclipse glasses you will hardly notice – daylight looks almost normal.
Where the Sun is
At maximum the Sun is 42° above the horizon in the south-east (azimuth 116°). The Sun is high, so most outdoor spots with a clear view upwards will work.

Safety
- Never look directly at the Sun without certified eclipse glasses that meet the ISO 12312-2 standard. Ordinary sunglasses do not protect your eyes, not even several pairs on top of each other.
- The eclipse is partial here. It is never safe to look at the Sun without protection – not even when almost all of it is covered.
How we calculated this
The times are calculated for the place's coordinates and elevation (GeoNames) with Skyfield and the JPL ephemeris DE421 – the same program that makes the paid guide. The calculation is checked against NASA eclipse data (Fred Espenak, NASA GSFC). The times assume a clear sky; nobody can forecast the weather this far ahead.
