03 · DIRECTION
Where do I look?
At maximum the Sun is just 6° above the horizon to the south-west. You will need a clear, flat horizon — over water, or from high ground.
The Sun's height and bearing at maximum, from Rothera. The horizon is at 0°.
THE EXPERIENCE
What it will actually be like
The Sun disappears entirely. For those few minutes the corona is visible around a black disc, bright stars and planets come out, and the horizon takes on the colours of a sunset in every direction at once. It is not a deeper version of a partial eclipse; it is a different event, and the difference arrives in the last few seconds.
SAFETY
Looking at it without hurting yourself
Keep a certified solar filter on for every part of the eclipse except totality itself. During totality, and only then, it is safe to look with the naked eye — and the filter must go back on the instant the Sun reappears.
Sunglasses, smoked glass, exposed film and phone screens are not filters. If you can see anything else through it, it is not dark enough.
04 · POSITION
