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.

B. Proton Events
None.
C. Geomagnetic Activity Summary
The geomagnetic field was quiet to
active with an isolated period of minor storm conditions during the
14/0900-1200 UTC synoptic period, due to a combination of waning
negative polarity CH HSS effects and a prolonged period of -Bz
associated with the probable arrival of the 10 Apr transient
feature.
