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 greater than 10 MeV proton event accompanied
the long duration M1 flare and CME that occurred at 25/1514Z. The
proton event began at 25/1855Z and remains in progress. The peak so
far was 55 pfu at 25/2305Z.
C. Sammanfattning av geofysisk aktivitet
The geomagnetic field was at
active to severe storm levels. The shock observed at the ACE
spacecraft on 24/0600Z was followed by a prolonged period of
southward IMF Bz that lasted through midway on 25 July. Bz ranged
from -10 to -20 nT for much of this period, while solar wind speed
was elevated in the 550 to 700 km/s range. Consequently, severe
geomagnetic storm levels were observed at all latitudes. It is
likely that this activity was associated with the complex series of
CMEs observed on 22 July. Late in this period, a discontinuity in
the solar wind suggested that transient flow from the multiple CME
activity on 23 July had arrived.
