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
Greater than 100 MeV and 10 MeV proton events
occurred in association with today's major flare. The greater than
100 MeV event started at 26/0555 UTC, reached a peak of 50 pfu at
26/0720 UTC, and ended at 26/1935 UTC. The greater than 10 MeV event
started at 26/0605 UTC, reached a peak of 779 pfu at 26/1115 UTC,
and continues in progress.

F. Kommentarer
The particle event discussed in part B. was associated with a GLE starting at about 26/0600 UTC and reaching a maximum at about 26/0620 UTC (8% at Apatity, Oulu, and McMurdo, and 2% at Moscow). A Polar Cap Absorption event (PCA) also occurred, reaching a peak absorption of about 9 dB at 26/1115 UTC and continuing in progress at this writing.
