Bülletään

Solar activity is eruptive with 6 C-flares in the past 12 hours. Four C-flares originated from NOAA AR1698 and two C-flares came from an unnumbered region near AR1700. Solar activity is expected to remain eruptive for the next 24 hours, mainly caused by AR1698. C-flares are very likely, but there is also a slight chance for an M-flare. AR1698 is approaching the west limb, so if it erupts a proton event is possible. The solar wind is getting stable again; in the past 24 hours the speed has decreased from 750 km/s to about 500 km/s. The interplanetary magnetic field has returned to about 10nT, with a positive Bz-component. Geomagnetic conditions are expected to be quiet for the next 48 hours.
