Aurora Borealis in Arizona
An severe geomagnetic storm, caused by an enormous explosion on the sun (a Coronal Mass Ejection, technically) last week, peaking on about 15 May 2005, caused an Aurora Borialis at both poles and as far toward the equator as Arizona, where I suppose we could call them Aurora Temporalis. The picture shown here was a ten minute exposure, taken with a special camera setup in Payson, AZ, at about 2 am on the 15th, by Chris Schur.
