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 is expected
to be at unsettled to active levels with minor storming conditions
likely on day one (13 May) with the onset of a CH HSS. On day two
through three (14 - 15 May), the high speed stream is expected to
taper off, bringing geomagnetic
conditions below minor storming
thresholds.
