In the past 24 hours, Catania sunspot group 88 (NOAA AR 2192) produced two
X-class flares: X1.0 peaking at 17:08 UT yesterday and X2.0 peaking at
10:56 UT today. Neither of the flares seems to be associated with an
Earth-directed CME. The area of the Catania sunspot group 88 increases
again, and it maintains the beta-gamma-delta configuration of its
photospheric magnetic field, so we expect the flaring activity up to
X-level from this sunspot group. As the Catania sunspot group 88 is
currently situated in the western solar hemisphere, a major eruption in
this active region may lead to a proton event. A long filament in the
northern hemisphere is continuing its passage across the solar central
meridian. Its possible eruption may lead to an Earth-directed CME. The
Earth is currently inside a slow (around 370 km/s) solar wind flow with
slightly elevated (around 7 nT) interplanetary magnetic field magnitude.
The geomagnetic conditions are quiet and are expected to remain  so, with
isolated intervals of active (K = 4) geomagnetic conditions possible but
not very likely.
