SIDC SOLAR BULLETIN 17 Jun 2004, 1230UT
SIDC FORECAST (valid from 1230UT, 17 Jun 2004 until 19 Jun 2004)
SOLAR FLARES  : Eruptive (C-class flares expected, probability >= 50%)
GEOMAGNETISM  : Quiet (A<20 and K<4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 17 Jun 2004  10CM FLUX: 115 / AP: 011
PREDICTIONS FOR 18 Jun 2004  10CM FLUX: 117 / AP: 012
PREDICTIONS FOR 19 Jun 2004  10CM FLUX: 117 / AP: 012
COMMENT: Catania sunspot groups 55 and 56 (NOAA 0634 and 0635) have remained
fairly quiet, despite their magnetic complexity. The largest flare produced in
the past 24 hours was a C1.2 from Catania 55 earlier today. This was also the
only C-class flare since yesterday's forecast. Since both sunspot groups are
growing and remain magnetically complex, it is very likely that we'll see some
more C-class flares from these regions, while there is also a small chance for
an M-class flare.
Geomagnetic conditions have remained quiet the past 24 hours and are expected
to remain so. Although the solar wind speed is still high at more than 500 km/s,
the north-south component of the IMF is hovering near zero and the density is
quite low, so that geomagnetic effects of this high speed solar wind stream
remain limited.
