Explanatory Notes for the Above Table
-------------------------------------
This table shows the predictions for most of the critical parameters, in
terse format. First column is the date. Second column is the predicted
solar flux for the next 10 days. Third through sixth columns represent
predicted HF radio propagation conditions for the LOw, MIddle, HIgh, and
POlar latitude paths, where BO represents BlackOut conditions (essentially
useless propagation), VP represents Very Poor conditions, P represents Poor
conditions, F means Fair conditions, G is Good (normal) propagation, and VG
is Very Good conditions. The seventh column shows the probability of daylit
circuits being affected by flare-induced short wave fadeouts. The eigth
column shows the predicted global MUF level as a percentage above or below
expected normal levels (ex. +10 means the MUF on that date could be 10
percent ABOVE-NORMAL, whereas a 00 means the MUF should remain at normal
levels). The ninth column is the confidence that the forecasts for the
given
date are accurate (100 means the forecasts will be 100 percent accurate, and
50 means there is a 50 percent chance the forecast will be accurate). The
tenth column shows the predicted peak planetary geomagnetic K-index for the
given day. The eleventh column shows the predicted 24-hour planetary
geomagnetic A-index. And the twelfth through fourteenth columns predict the
level of auroral activity that will be visible from the LOw, MIddle and HIgh
latitude regions, where NV means Not Visible, LO means LOw levels of auroral
activity may be visible, MO means MOderate intensity auroral activity may be
visible, and HI means HIgh levels of auroral activity may be possible to
observe.

CONFIDENCE LEVEL: 65%
DISCUSSION:
Levels of geomagnetic activity are expected to be dominantly quiet to
slightly unsettled over the next 10 days. Effects from solar Region 8113
did
not materialize during the last forecast period due to simplification of the
region. Additional simplification and decay is expected as the region moves
toward the western solar limb. As a result, this forecast is based
primarily
on the assumption that few (if any) interplanetary disturbances will be
spawned by this decaying region.
