Thanks Herb, but I would caution everyone about the auroral rings
in this program...the author says:
"The approximate auroral rings may be displayed. Since these rings vary
continuously due to position of the sun and level of solar wind, the rings
are approximated as being 2000 miles from the geomagnetic poles."
This sounds like the rings are fixed. DXAID shows auroral rings for
any user selected value of the K-index from 0 to 9. But who can complain if
AZMAP is free?
