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 has been at
unsettled to minor storm levels. A coronal hole, which has induced
a high-speed solar wind stream for the last few days, is in its
final stages, but continues to impact the Earth's magnetic field.
