THE EXPERIENCE
What it will actually be like
Only 35.5% of the Sun is covered, so nothing about the daylight in Porto will change. Through a safe solar filter the Moon shows as a shallow notch on one edge of the disc.
SAFETY
Looking at it without hurting yourself
A certified solar filter stays on for the whole eclipse. The Sun is never completely covered here, and what remains is as dangerous to look at as an uneclipsed Sun. Sunglasses are not a filter.
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
Should I travel?
The path passes 2,974 km to the north-east of Porto and is 461 km wide. Only inside it is the Sun covered completely.
