Partial solar eclipse, 12 June 2029

Visible from the Arctic, Scandinavia, Alaska, northern Asia, northern Canada.

At greatest eclipse the Moon is 393,682 km away and 30.3 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 3.7% 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.
