eventually reconnect somewhere, but that somewhere could be a very
long way out. I did find these little tidbits :
"Coronal holes appear dark areas of the corona when viewed in
ultraviolet light. This elongated hole area from January 11, 2002 was
one of the largest seen by SOHO. Although they are usually located at
the poles of the Sun, coronal holes can occur other places as well.
The magnetic field lines in a coronal hole extend out into the solar
wind rather than coming back down to the Sun's surface as they do in
other parts of the Sun. Thus, they are often the source of strong
solar wind gusts that carry solar particles into space and possibly
impact the Earth."
Lengthy, but interesting :

As you read these, you may get a sense that we don't exactly know
everything there is to know about the sun. That would be quite
correct. Scientists didn't know that such things as Coronal Mass
Ejections and coronal holes even existed until the 1970's when the
first solar observing and X-ray satellites were launched. Solar and
geomagnetic physics are fields of study within themselves, and
numerous books have been written on the subjects. Albert Einstein
said that how Earth's magnetic field is generated was one of the great
mysteries of physics. That statement still holds true today. While
it's assumed that it has something to do with the motion and
convection of liquid iron deep within Earth's interior, nobody is sure
of the exact mechanism.
