FAST WARNING 'PRESTO' MESSAGE  from the SIDC (RWC-Belgium) 2014 Apr 15
12:51:58

Nine sunspot groups were reported by Catania today. Catania sunspot group
25 (NOAA AR 2036) was responsible for the most of the flaring activity
during the past 24 hours. The strongest flare of this period, however, was
produced by the Catania sunspot group 24 (NOAA AR 2035) that showed rapid
magnetic flux emergence in the past several hours: the C8.6 flare peaking
at 09:23 UT. We expect further flaring activity on the C-level from these
two active regions, with a good chance for an M-class event.
The Earth
is currently inside a slow (around 350 km/s) solar wind flow with weak (2-3
nT) interplanetary magnetic field magnitude. The geomagnetic conditions are
quiet and are expected to remain so.
