:Solar_Analysis:
Analysis of Solar Active Regions and Activity from 18/2100Z to
19/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C4 event observed at
19/1932Z from Region 2032 (N12W83). There are currently 12 numbered
sunspot regions on the disk.
#
:Solar_Forecast:
Solar Activity Forecast: Solar activity is likely to be moderate
with a slight chance for an X-class flare on day one (20 Apr) and
expected to be low with a chance for M-class flares on days two and
three (21 Apr, 22 Apr).

#
:Geophysical_Activity:
Geophysical Activity Summary 18/2100Z to 19/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
583 km/s at 19/1858Z. Total IMF reached 10 nT at 18/2118Z. The maximum
southward component of Bz reached -6 nT at 18/2345Z. Protons greater
than 10 MeV at geosynchronous orbit reached a peak level of 58 pfu at
19/0105Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 242 pfu.
#
:Geophysical_Forecast:
Geophysical Activity Forecast: The geomagnetic field is expected
to be at unsettled to major storm levels on day one (20 Apr), quiet to
minor storm levels on day two (21 Apr) and quiet to active levels on day
three (22 Apr). Protons are expected to remain above the 10 pfu
threshold on days one and two (20-21 Apr) and have a chance of crossing
threshold on day three (22 Apr).
