SDF Number 122 Issued at 2200Z on 02 May 2014
IA. Analysis of Solar Active Regions and Activity from 01/2100Z to
02/2100Z: 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
02/0940Z from Region 2047 (S18W28). There are currently 5 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be low with
a chance for M-class flares on days one, two, and three (03 May, 04 May,
05 May).
IIA. Geophysical Activity Summary 01/2100Z to 02/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed,
as measured by the ACE spacecraft, reached a peak speed of 391 km/s at
01/2304Z.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on day one (03 May) and quiet to unsettled levels
on days two and three (04 May, 05 May).
