SIDC SOLAR BULLETIN 28 Jun 2010, 1122UT
SIDC FORECAST (valid from 1230UT, 28 Jun 2010 until 30 Jun 2010)
SOLAR FLARES  : Quiet conditions (<50% probability of C-class flares)
GEOMAGNETISM  : Quiet (A<20 and K<4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 28 Jun 2010  10CM FLUX: 074 / AP: 016
PREDICTIONS FOR 29 Jun 2010  10CM FLUX: 075 / AP: 019
PREDICTIONS FOR 30 Jun 2010  10CM FLUX: 076 / AP: 021
COMMENT: The only sunspot group on the solar disc (Catania number 93,
NOAA AR 1084) is unlikely to produce a C-flare. The Earth is currently
inside the fast (540 km/s) solar wind stream with average (5 nT)
magnitude of the interplanetary magnetic field. The fast stream
originates from a low-latitude extension of the polar coronal hole in
the northern hemisphere. We expect quiet to active geomagnetic
conditions, with possible isolated intervals of minor geomagnetic storm
as the fast stream is expected to continue over the next 48 hours.

TODAY'S ESTIMATED ISN  : 007, BASED ON 17 STATIONS.
