[PW] Orbiting solar shades

[Karen Lofstrom]

I'm trying to access a November 2006 publication in the PNAS journal,
titled: Feasibility of cooling the Earth with a cloud of small
spacecraft near the inner Lagrange point (L1) It's at
<http://intl.pnas.org/cgi/content/short/0608163103v1> I'm not at a
university and I don't want to pay $10 for a look at one article --
particularly when I'm interested in the figures, not so much the text.
I wonder what the cloud would look like from earth, as I'm interested
in featuring it in a science fiction thingie I'm writing. Not a major
part of the story, just something the folks on the ground see and take
completely for granted.

This is a long shot, but if any of you have access to the article and
could send me any relevant illustrations, or point me to a place where
such might be found, or, heck, even speculate yourselves about what it
might look like from the ground, I would appreciate it.
