COMMENT: Catania sunspot group 96 (NOAA 0431) continues to decline, albeit
slowly. Since yesterday's report, this group has again been the seat of several
C-flares. It is expected to continue generating C-flare activity with a small
chance for an isolated M-class event. It remains the most active sunspot group
on the disk. Activity in the new groups 04 and 05 at the eastern limb is so far
confined to small-scale events. The solar wind speed continues it steady (nearly
linear) decline. It currently stands at 420 km/s approximately. The
interplanetary magnetic field is firmly northwards. Geomagnetic conditions are
quiet and are expected to remain so for the following days.
