                            CONFIDENCE LEVEL: 70%

NOTES:
       Predicted geomagnetic activity is based heavily on recurrent
phenomena. Transient energetic solar events cannot be predicted reliably over
periods in excess of several days.  Hence, there may be some deviations from
the predictions due to the unpredictable transient solar component.

NOTES:
     This graph is determined by plotting the greater of either the planetary
     A-index or the Boulder A-index.  Graph lines are labelled according
     to the severity of the activity which occurred on each day.  The left-
     hand column represents the associated A-Index for that day.
     Q = Quiet, U = Unsettled, A = Active, M = Minor Storm,
     J = Major Storm, and S = Severe Storm.

NOTES:
     The 10.7 cm solar radio flux is plotted from data reported
     by the Penticton Radio Observatory (formerly the ARO from
     Ottawa).  High solar flux levels denote higher levels of
     activity and a greater number of sunspot groups on the Sun.
     The 90-day mean solar flux graph is charted from the 90-day
     mean of the 10.7 cm solar radio flux.

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.
