NOTES:
      These VHF DX prediction charts are defined for the 30 MHz to 220 MHz
bands.  They are based primarily on phenomena which can affect VHF DX
propagation globally.  They should be used only as a guide to potential
DX conditions on VHF bands.  Latitudinal boundaries are the same as those for
the HF predictions charts.  For more information, request the document
"Understanding Solar Terrestrial Reports" from: "Oler@Rho.Uleth.Ca" or
"COler@Solar.Stanford.Edu".  This document, as well as others and related
data and forecasts exist on the STD BBS at: (403) 756-3008.
