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
Solar activity is expected to be
moderate. Region 9893/9901 complex has been active and has two
delta configurations. The potential for M-class events is good.
Region 9906 and 9907 are developing and have a slight chance of
M-class events.
