:Solar_Analysis:
Analysis of Solar Active Regions and Activity from 16/2100Z to
17/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a M7.2 event that was in
progress as of this report from Region 3685 (S13E50, Ds0/beta-gamma).
There are currently 12 numbered sunspot regions on the disk.
#
:Solar_Forecast:
Solar Activity Forecast: Solar activity is expected to be low with
a chance for M-class flares and a slight chance for an X-class flare on
days one, two, and three (18 May, 19 May, 20 May).

#
:Geophysical_Activity:
Geophysical Activity Summary 16/2100Z to 17/2100Z: The geomagnetic
field has been at quiet to major storm levels for the past 24 hours.
Solar wind speed reached a peak of 497 km/s at 17/1849Z. Total IMF
reached 17 nT at 17/1404Z. The maximum southward component of Bz reached
-15 nT at 17/1651Z.  Protons greater than 10 MeV at geosynchronous orbit
reached a peak level of 7 pfu at 17/0250Z. Electrons greater than 2 MeV
at geosynchronous orbit reached a peak level of 205 pfu.

:Geophysical_Forecast:
Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to minor storm levels on day one (18 May) and quiet to
active levels on days two and three (19 May, 20 May). Protons greater
than 10 Mev have a slight chance of crossing threshold on day one (18
May).
