Istanbul and the path of totality
The shaded band is the path of totality, the dashed line its centre, where totality lasts longest. Coastlines, rivers and borders: Natural Earth.
Istanbul is far outside the path of totality: its nearest stretch is 1,110 km to the south-west, and on the centre line there, 1,240 km away, totality lasts 6 min 15 s.
The nearest place in the path with its own page here is Benghazi, 1,270 km to the south-west, with 6 min 9 s of totality.
What you will see
Through eclipse glasses, the Moon's edge first touches the Sun at 11:27:16. By 12:39 it has turned the Sun into a crescent, with 59.4% of its face covered, and at 13:50:52 it moves clear. The whole eclipse lasts 2 h 24 min.
Outside the path some of the Sun always shows, and even a thin crescent is far too bright to look at, so glasses stay on from start to finish. The Sun is 66° up in the south: any open spot with a clear view that way works.
How to watch safely
- Wear eclipse glasses that meet the ISO 12312-2 standard whenever any part of the Sun is showing. Sunglasses, however dark, are not safe.
- Never look through binoculars, a telescope or a camera without a proper solar filter on the front.
- A pinhole projector works anywhere: a small hole in card throws an image of the Sun onto paper behind it.
- There is no safe moment without glasses in Istanbul: even at 59.4% a crescent of the Sun is still showing.
