Tue evening, I went to a talk on Auroras and Solar Storms.  It was targeted 
as the general public so they didn't get into any technical details.

One of the pictures showed a GPS setup.  They were using it to measure free 
electrons in the ionosphere.


A friend found this in case anybody wants gory details:
