FAST WARNING 'PRESTO' MESSAGE  from the SIDC (RWC-Belgium) 2014 Apr 16
12:18:21

Nine sunspot groups are reported on the Sun today. Four of them have
beta-gamma configuration of the photospheric magnetic field: Catania
numbers 23, 24, 25, and 26 (NOAA ARs 2034, 2035, 2036, and 2037,
respectively). These four groups produced numerous C-class flares during
the past 36 hours. None of the flares was associated with a CME. The
strongest flare of today is the C5.2 flare peaking at 08:44 UT in the
Catania sunspot group 24 (NOAA AR 2035). The solar soft X-ray background
flux is currently around the C1 level. We expect further flaring activity
on the C-level from these four sunspot groups, with a good chance for an
M-class event.
The Earth is currently inside a slow (around 320 km/s)
solar wind flow with weak to average (3-4 nT) interplanetary magnetic field
magnitude. The geomagnetic conditions are quiet and are expected to remain
so.
