Bulletin

Solar activity was very low. A new emerging active region NOAA AR 2722 (Bxo, Beta) has some potential to produce C-class flares. No earth- directed coronal mass ejections (CMEs) were observed. The greater than 10MeV proton flux remained at background levels over the past 24 hours. Solar activity is expected to remain low. Solar wind parameters variations decreased after the passage of the co- rotating intercation region. Solar wind speed decreased from about 590 to 530 km/s. The total interplanetary magnetic field is below 6 nT. Bz varied between -3 and +5 nT. Geomagnetic conditions gradually decreased from the moderate storm level yesterday till quiet conditons observed now. Geomagnetic conditions are expected to be mostly quiet from now.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 014, gebaseerd op 15 stations.
