Total solar
eclipses are very rarely observed. That's not to
say that they don't occur often--they do. Because
the cone-shaped umbra's tiny tip barely brushes the
surface of the earth, each eclipse only covers a
very small area. Add to this that 71 percent of the
earth's surface is covered with water, and you
realize that a very tiny portion of the earth's
population ever experiences a total eclipse. Either
you have to by coincidence be in the right place at
the right time, or you must be willing to travel
great distances to be at the right place at the
right time. I fall into the second category. So far
I've been lucky enough to see three eclipses (out
of three attempts!). To view them I have found
myself in the middle of Canada's Lake Winnipeg in
midwinter, in equatorial Africa in Kenya, and at
the southernmost tip of Baja California. As you can
see, chasing eclipses is a great excuse to travel!
You'll always end up somewhere
interesting.
Every
eclipse traces out a long path as the shadow moves
across the surface of the earth. Below is a view of
the upcoming eclipse in February.
As you can
see, the two central parallel lines that make up
the path of the umbra cover quite a distance. The
much wider area shows the path of the larger
penumbra, where a partial eclipse can be seen.
Let's follow along this path and put in some closer
maps as we approach Aruba--our outpost for this
eclipse.
The shadow
first touches down near the equator out in the
Pacific Ocean. It travels eastward and first hits
land at the Galapagos Islands, where it brushes
past the northenmost of those famous islands.
Continental landfall occurs in Panama and Colombia,
where the eclipse passes over the cities of
Montería, Sincelejo, Magangué,
Valledupar, and Maracaibo.

The path
nicks northern Venezuela and then heads out into
the Carribean, where it will pass over the islands
of Aruba, Curaçao, Montserrat, Antigua, and
Guadeloupe. Here's a closer view of northern
Venezuela, Aruba, and
Curaçao.
