Geophysical report
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.

C. Geomagnetic Activity Summary
The geomagnetic field was quiet to
active. The high speed coronal hole stream that became geoeffective
on 05 May continues to buffet the geomagnetic field. Frequent
southward IMF Bz oscillations over the last 24 hours are responsible
for the most disturbed periods. The high speed stream does appear to
be subsiding: solar wind speed decreased to below 500 km/s late in
the period.
