SIDC SOLAR BULLETIN 19 May 2006, 1246UT
SIDC FORECAST (valid from 1230UT, 19 May 2006 until 21 May 2006)
SOLAR FLARES  : Quiet conditions (<50% probability of C-class flares)
GEOMAGNETISM  : Active conditions expected (A>=20 or K=4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 19 May 2006  10CM FLUX: 075 / AP: 009
PREDICTIONS FOR 20 May 2006  10CM FLUX: 077 / AP: 008
PREDICTIONS FOR 21 May 2006  10CM FLUX: 079 / AP: 004
COMMENT: The Sun is still quiet. A new active region appeared in the
Eastern hemisphere (Catania sunspot group 41, no NOAA number yet). The
Earth is currently inside the fast flow from a coronal hole. Isolated
intervals of active geomagnetic conditions (K = 4) are thus possible.
