KN4LF Solar Space Weather and Geomagnetic Outlook

Posted 1515 UTC August 04, 2004 

During the past eight day period geomagnetic conditions have been quiet Kp-0, 1, 2 to intermittently unsettled Kp-3. The unsettled conditions have occurred thanks to a high speed solar stream from small but geoeffective (Earth facing) Coronal Hole #107. 

Daily solar flux and sunspot numbers have fallen back to low levels. As of Wednesday August 04, 2004 the daily solar flux level stood at 86, 85 and 87 and the daily sunspot number was 42. These numbers should once again begin rising in 3-4 days. 

Solar flaring has been in the C class range with only one visible sunspot group, #10655 in geo-effective position at S09E03 with a beta-gamma magnetic configuration. This sunspot group is slowly growing and may produce isolated M class solar flares. Sunspot group number 10654 is now rotating around the west limb of the Sun. 

Solar and space weather conditions should continue rather quiet through at least August 07-08, 2004. Then guess what? Sunspot group #10649 once again rotates around the east limb of the Sun. In it's trip around the far side of the Sun the sunspot group has held together quite nicely. So after the 08th we can expect a probable return of major solar flaring and geomagnetic storming.
