OF THE SUN COVERED
Almost all of the Sun goes. The light weakens and cools noticeably, shadows sharpen, and the temperature drops — but it does not get dark, and the remaining sliver is still blinding.

Where do I look?
At maximum the Sun stands 47° above the horizon to the south-east — high enough to clear most buildings and trees.
The Sun's height and bearing at maximum, from Monterrey. The horizon is at 0°.
THE EXPERIENCE
What it will actually be like
With 99.9% of the Sun covered the light noticeably weakens and cools, shadows grow sharp-edged, and the temperature drops. Gaps between leaves project rows of crescents onto the ground. The Sun remains dangerous to look at throughout.
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?
Monterrey falls just outside the path, which passes 54 km to the north-east and is 102 km wide. A short journey in that direction would reach it.
