Ceuta
360º viewer: will that building block it?
Point your phone's camera where you plan to be on 2 August and we mark the exact spot in the sky where the Sun will be at 10:47, the moment of maximum eclipse in Ceuta. It answers what no table can: whether a building, a crane or a hillside will get in the way from that balcony, terrace or viewpoint.
Camera sun viewer
Point your phone where you plan to be and use the camera to check whether a building, a tree or a hill will block the eclipse.
Mobile only, with a camera and a compass. Nothing the camera sees is recorded or leaves your phone.
Computing for Ceuta
The city's point already works. Refining with GPS shifts the Sun's direction by fractions of a degree: it matters when you are judging one specific balcony.

How accurate it is
How to use it
- Stand where you plan to be on eclipse day. The viewer answers for that point, not for the city.
- Open the camera and turn, following the amber arrows that tell you how many degrees are left, until the circle sits inside the reticle.
- Look at what is in that direction and at that height. If a building is there, the spot is no good: totality lasts minutes and the Sun does not move far enough to clear it.
- Check the start and the end too. The blue line is the Sun's path through the whole eclipse, and "Moment" jumps to any of the five contacts: between the first and the last the Sun shifts about 24° and climbs almost 30°, so a roof that does not block maximum may block the rest.
- If your phone has no compass or gives no absolute heading, use manual adjustment: the viewer opens all the same.
