Hi Ron,

That is a great idea. I will get an Orbitsphere page up as soon as I can. I certainly understand what a great circle is, but I think I will need to refresh my understanding of those current vector fields, like the BECVF.

BTW, Jeff contacted me this evening about another subject, so I mentioned the great circle thing to him too.
