COMMENT: Returning sunspot group Catania 05/NOAA 0720 is still not
visible on the solar disk, but its loop system is now prominent in EIT
images. The group has already produced several C-class flares, the
largest a C7.1 round midnight. We expect at least C-flares from now on,
with a good chance for M-flares to follow soon.
Geomagnetic conditions are quiet. The solar wind speed is now at 400km/s
and rapidly decreasing. A small equatorial coronal hole may push it back
up later today and tomorrow. Active conditions may be reached.
