SIDC SOLAR BULLETIN 17 Aug 2005, 1230UT
SIDC FORECAST (valid from 1230UT, 17 Aug 2005 until 19 Aug 2005)
SOLAR FLARES  : Quiet conditions (<50% probability of C-class flares)
GEOMAGNETISM  : Quiet (A<20 and K<4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 17 Aug 2005  10CM FLUX: 077 / AP: 014
PREDICTIONS FOR 18 Aug 2005  10CM FLUX: 078 / AP: 009
PREDICTIONS FOR 19 Aug 2005  10CM FLUX: 079 / AP: 007
COMMENT: Solar activity is very quiet. The only noteworthy sunspot
group is Catania #22 (NOAA 0797) which has a beta-gamma magnetic
configuration, no major flares are expected. The influence of the
coronal hole is still visible in recordings of the solar wind speed,
elevated at about 650 km/s. The magnetic field strength of the solar
wind at 1 AU diminished to about 5 nT now and is predominantly northward
oriented. After 2 periods of active conditions, most stations now report
quiet geomagnetic conditions. We expect quiet conditions for the next
days.
