latest solar flare activity Aug 27 2012
SDF Number 240 Issued at 2200Z on 27 Aug 2012
IA. Analysis of Solar Active Regions and Activity from 26/2100Z
to 27/2100Z: Solar activity was very low. Region 1558 (N18E78)
produced the largest flare of the period, a B9 at 27/0821Z. Three
new regions were numbered: Region 1556 (S12W79) an Axx-alpha type
group; Region 1557 (N17E38) a Bxo-beta type group; and Region 1558 a
Bxo-beta type group. The remaining numbered regions were stable and
quiet. Several CMEs were observed however none appear to be
Earth-directed.
IB. Solar Activity Forecast: Solar activity is expected to be very
low to low with a slight chance for moderate activity for the next
three days (28-30 August).
IIA. Geophysical Activity Summary 26/2100Z to 27/2100Z:
The geomagnetic field was quiet to unsettled.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be quiet to unsettled with a slight chance for active
conditions on days 1-2 (28-29 August) due to continued effects from
a coronal hole high speed stream. On day 3 (30 August), conditions
are expected to return to predominately quiet levels.
