Geofysisk rapport
Any mentioned solar flare in this report has a scaling factor applied by the Space Weather Prediction Center (SWPC). Because of the SWPC scaling factor, solar flares are reported as 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.

B. Protonstormar
A new surge of high energy protons followed the
X-10 flare, enhancing the existing greater than 10 MeV and greater
than 100 MeV proton events from the X17 flare on the 28th. This
enhancement reached 110 pfu (29/2310Z) in the greater than 100 MeV
level, and 3300 pfu (30/1935Z) in the greater than 10 MeV level. A
polar cap absorption continues and the proton event remains in
progress.
C. Sammanfattning av geofysisk aktivitet
The geomagnetic field was at
predominantly minor to severe storm levels. The intense geomagnetic
storm that began at 29/0611Z continued through the first half of
this period. Severe levels were observed from 30/0000 - 0600Z. A
short-lived "lull" (K5-6) in activity preceded the onset of another
severe geomagnetic storm. The very fast CME from the X10 flare that
peaked at 29/2049Z impacted the magnetic field at around 30/1600Z -
a remarkably fast 19-hour transit from Sun to Earth. Sustained
southward IMF Bz in the -15 to -30 Nt range is assuring a severe
response. A Forbush decrease at around 20% remains in progress.
