Bulletin

Solar activity remains to be low, with only two low C-class flares reported in the past 24 hours. The C1.1 flare observed at the East solar limb this morning (peaking at 04:19 UT) was associated with the coronal EUV wave and rather narrow CME. We do not expect significant change in the level of the solar activity. Low C-class flares are possible in the coming hours. No Earth directed CMEs were observed in the last 24 hours. The Earth is currently inside of the fast flow associated with the strongly extended northern polar coronal hole. During last 36 hours the solar wind speed is slowly increasing, with the current value of about 640 km/s. The interplanetary magnetic field magnitude is slightly elevated and it amounts about 14 nT. We expect further increase of the solar wind speed which, together with the possibly negative values of the Bz component of the interplanetary magnetic field, might induce active to minor storm geomagnetic conditions in the coming hours.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 056, gebaseerd op 14 stations.
