Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 149 Issued at 2200Z on 29 May 2014

IA.  Analysis of Solar Active Regions and Activity from 28/2100Z to
29/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C1 event observed at
29/0430Z from Region 2071 (S10W61). There are currently 4 numbered
sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is expected to be very low
with a chance for a C-class flares on days one, two, and three (30 May,
31 May, 01 Jun).

IIA.  Geophysical Activity Summary 28/2100Z to 29/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
395 km/s at 29/1057Z. Total IMF reached 8 nT at 29/1910Z. The maximum
southward component of Bz reached -7 nT at 29/0921Z.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one and two (30 May, 31 May) and quiet to
unsettled levels on day three (01 Jun).
