> Geomagnetic activity is increasing, now, due to the
> influence of fast wind coming from the coronal hole
> located in the central meridian of the Sun.  The
> rest of today's geomagnetic activity will be unsettled
> to active (up to a Kp of 5).  This will degrade the
> higher HF bands for the next two days.  By 11-XI-2003,
> a large coronal hole which is rotating into
> geoeffective position will inhance the solar wind
> further, causing active to minor geomagnetic storm
> conditions.
> 
> Three new sunpots have appeared on the Sun (Catania
> numbers 86, 87, and 89).  These are now growing and
> have what is known as a "beta magnetic configuration."
> The may become a source of flares, at least C-class at
> this time, causing some minor radio degradation on the
> lower HF bands on the sunlit side of the earth.
> 
> The 10.7-cm flux is now expected to rise, again, with
> these new sunspots.  Expected flux levels are 93, 95,
> and 98 for today through Tuesday.  But, with the
> increased geomagnetic activity, the higher bands will
> still suffer.
