My new web page server host http://www.aplus.net/ proved to be unreliable in every aspect so I dumped them yesterday evening. My other web page server host has been up in parallel for the past three months and I will be using them again solely. Sorry for any inconvenience that this may have caused.
So the new (old) web page URL's are as follows:

Highlights of Solar and Geomagnetic Activity
19 - 25 October 2009
Solar activity was very low to low. The week began with a spotless disk void of activity. However, new Region 1029 (N15, L=211, class/area Dsi/130 on 25 October) emerged on the disk on 23 October and produced numerous B-flares on 24-25 October as well as a C-flare
at 25/0226 UTC. The group showed steady growth that was continuing at the end of the highlights interval. In addition, Region 1028 (N27, L=206, class/area Axx/10 on 23 October) emerged on 20 October, decayed to plage on 21 October, re-emerged with one spot on 23
October, and then decayed to plage for the remainder of the interval.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at normal levels for most of the period with the exception of a brief period at moderate levels on 25 October.
The geomagnetic field began the period at quiet levels. Activity levels increased to predominantly unsettled to active on 22 October following a sudden impulse at 22/0019 UTC (11 nT on the Boulder magnetometer), and continued to be elevated through 23/1200 UTC.
Isolated minor and major storm periods were observed at high latitudes during this interval. Quiet levels predominated thereafter until late on the 24th when there was a small increase to quiet to unsettled levels which continued through 25/1500 UTC. Activity levels returned to quiet levels thereafter through the remainder of the period. Solar wind observations at the ACE spacecraft showed a weak shock at 21/2309 UTC which was followed by a slow increase in
velocity and enhanced interplanetary magnetic field (IMF). The southward component of the IMF ranged typically between +/- 6 nT with peaks around -9 nT following the shock and continuing through 23/0950 UTC. The solar wind velocity jumped from 270 km/s up to 340
km/s at the time of the shock and showed a slow increase through mid-day on the 24th with peak velocity around 420 km/s. Although there was some uncertainty the most likely source for this disturbance was the faint halo CME associated with the EIT wave that occurred around 17/1935 UTC as reported in last week's highlights. A second disturbance in the solar wind was seen beginning at 24/1630 UTC and lasting through mid-day on the 25th; the solar wind signatures were consistent with a co-rotating interaction region followed by a weak high-speed stream associated with a positive polarity coronal hole. Peak Bz values were around -7 nT during the CIR (24/1500 UTC to 25/0000 UTC) and peak velocity reached about 490 km/s at 25/0830 UTC.
Forecast of Solar and Geomagnetic Activity
28 October - 23 November 2009
Solar activity is expected to be very low to low.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at normal levels through the period.
The geomagnetic field is expected to be predominantly quiet for 28 October through 6 November. An increase to quiet to unsettled is possible on 7 November due to a recurrent high speed stream. Activity levels should return to predominantly quiet levels for 8 November through 16 November. An increase to unsettled levels with a chance for active periods is expected on 18-21 November due another recurrent high speed stream. Activity is expected to return to mostly quiet levels for 22-23 November.
