Mal sehen, wie sich das noch entwickelt.

Das Wetter macht ja gerade fast ueberall nicht mit.

Recent activity

The geomagnetic field was inactive to quiet on November 6. Solar wind speed ranged between 312 and 350 km/sec. A weak solar wind shock was observed at SOHO at 02:22 on November 7. Solar wind speed increased abruptly from 315 to 355 km/sec. After a brief initial southward swing of the interplanetary magnetic field, the IMF has been mostly northwards resulting in only a mild increase in geomagnetic activity. This was likely the arrival of the CME observed after the M1 event in region 10696 on November 3.

Forecast

The geomagnetic field is expected to be quiet to major storm on November 7 due to several CME impacts. Minor to severe storming is possible late on November 7 or on November 8 when the largest CME arrives, the one observed after the M class events early on November 6. While two coronal hole streams are headed for Earth, none of them are likely to be noticed in the presence of the much more powerful CMEs.

Region 10696 decayed somewhat as the huge penumbra split into smaller penumbrae. There are still several magnetic structures within the main penumbrae and further major flares are possible.

Comment added at 10:17 UTC on November 7, 2004: A moderately strong solar wind shock was observed at ACE at 10:02 UTC with a sudden increase in solar wind speed from 340 to 420 km/sec. The interplanetary magnetic field initially swung strongly southwards. This was likely the arrival of the second halo CME observed on November 3. Further CME impacts are expected later today.
