[AZ-Observing] Re: Namibia Photos

Andrew,

The "fairy circles" at the edge of the Namib are different from creosote rings. 
 There is no central plant.  They are simply circular discontinuities in the 
grass, which would otherwise be a uniform blanket.  Many teams of botanists 
have investigated, and they invariably come away empty.

Here's a recent article from "New Scientist" on the subject.

Sorry for the off-topic-ness of this botanical aside.

I will be speaking at SAC in October and EVAC (at the Science Center) in 
December.

Tom
