Seriously, why push, why continue to derail the thread, does it really make sense to do so.
Please post on topic, if you have something to say other than anything about the Magnetosphere ,then send a U2U or personal email.
Joint USAF/NOAA Report of Solar and Geophysical Activity SDF Number 190 Issued at 2200Z on 09 Jul 2009 IA. Analysis of Solar Active Regions and Activity from 08/2100Z to 09/2100Z: Solar activity was very low. No flares occurred during the past 24 hours. Region 1024 (S09W65) was quiet and stable as it approached the west limb. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 08/2100Z to 09/2100Z: The geomagnetic field was mostly quiet. Solar wind started to increase at approximately 1700Z due to coronal hole effects. This resulted in an unsettled period for 1800Z to 2100Z. IIB. Geophysical Activity Forecast: The geomagnetic field is expected be quiet on day one (10 July). Day two (11 July) is expected to be quiet to unsettled due to possible coronal hole effects. Day three (12 July) is expected to be quiet. III. Event Probabilities 10 Jul-12 Jul Class M 01/01/01 Class X 01/01/01 Proton 01/01/01 PCAF green IV. Penticton 10.7 cm Flux Observed 09 Jul 069 Predicted 10 Jul-12 Jul 069/069/068 90 Day Mean 09 Jul 070 V.

Middle Latitudes Active 05/10/05 Minor storm 01/05/01 Major-severe storm 01/01/01 B. High Latitudes Active 10/15/10 Minor storm 05/10/05 Major-severe storm 01/01/01

Look at this huge peak in the plasma temperature:
, but i have no idea what it means.

K-indices of 5 or greater indicate storm-level geomagnetic activity around earth.

Things are getting interesting. This activity was forecast by SWPC a couple of days ago, they call it "unsettled".
The part of the simulation you're looking at (green circle) is a "view" down on the ionosphere from above the north pole. The circular area is where the magnetic field joins the Earth near the north pole. This is the region where the aurora appear.
The really interesting part of the simulation right now (07/09/09 22:12) is the magnetic field representation. See that place where the lines get "pinched" together close to the night side of the Earth. That could be an indication of a magnetic reconnection. This process allows the particles from the solar wind to get pulled toward the poles (creating the activity you noticed around the pole).
