Solar activity 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.

IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet for 16 October. Expect unsettled conditions
with isolated active periods for 17-18 October due to a recurrent
coronal hole.
