Yet the total phase ends very suddenly, with the lovely 'Diamond Ring' effect when the first segment of the photosphere re-appears. At once the hazards return. Photograph the eclipse by all means - but bear in mind that a camera involves a lens system, so that the same precautions must be taken. Use your camera without a filter only during the moments of totality. At this eclipse the total phase will last for no more than 2 minutes, seen along the central track - which crosses the Scilly Isles, most of Cornwall and South Devon, including Plymouth.
Clear skies are likely over the Black Sea area.
In our own West Country, we are at the mercy of the weather. Bear in mind that Cornwall and Devon will be overcrowded, to put it mildly. Moreover, all accommodation is already booked. Stars will appear, but the corona will shed about as much light as a full moon, so that there is no need to carry a torch - indeed, during totality the less 'light pollution' around the better. If you go to the West Country, and the sky is clear, you will have the experience of a lifetime.
