Annular solar eclipse, 1 June 2030
Visible from Europe, north Africa, the Middle East, Asia, the Arctic, Alaska, with the central track crossing Algeria, Tunisia, Greece, Turkey, Russia, northern China and Japan.
At greatest eclipse the Moon is 406,118 km away and 29.4 arcminutes across. The Sun, 31.5 arcminutes across, is near its smallest — Earth is close to aphelion at this time of year. The Moon is 6.8% narrower than the Sun in the sky, so it cannot quite cover it: a ring of Sun is left all the way round, and there is no corona and no darkness worth the name.
Never look at the Sun without a filter made for it. Eclipse glasses or a solar filter, not sunglasses and not a camera. The one exception is totality itself — the couple of minutes when the disc is completely covered — and only inside the path above.

Date, time and duration: NASA, Five Millennium Canon of Solar Eclipses (opens in a new tab). Angular sizes and the Moon's distance computed here, for 06:29:13 UT.
The globe is computed here from the same Sun and Moon as everything else on this site, by intersecting the Sun-Moon shadow axis with the Earth minute by minute. Four things about it are checked against NASA on every build: the time of greatest eclipse, the countries the line crosses, whether the cone reaches the ground at all — which is what makes an eclipse total rather than annular — and the length of totality, which comes out within a percent of NASA's on all eight. The Earth is modelled with its real shape here, flattened at the poles, which is what makes that last figure hold for the short grazing eclipses as well as the long ones. What is not modelled: refraction at the horizon, and the fact that a shadow lands on mountains rather than on sea level. For whether the track crosses your actual street, go to NASA's own map (opens in a new tab).
