Bulletin

NOAA AR 2665 (the only visible AR on the disk) produced multiple B class flares. This region continues to grow, C-class flares can be expected (and less likely M-flares). No Earth directed Coronal Mass Ejections (CMEs) have been detected. Solar protons have remained at background levels over the past 24 hours. Solar wind parameters reflected the continued influence of a high speed stream coming from the positive polarity coronal hole. Solar wind speed steadily increased from about 550 km/s to 670 km/s ( at 07:30 UT), later solar wind speed slightly decreased till 630 km/s. Total magnetic field abruptly decreased from about 8 to 4 nT today (04:30 UT), simultaneously variations of Bz component decreased from +7/+4 nT till +/-2 nT. Geomagnetic conditions ranged between Kp index 1-3 (NOAA) and local K index 1-4 (Dourbes) over the past 24 hours. Geomagnetic conditions are expected to be quiet to unsettled for the next few days.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 041, gebaseerd op 17 stations.
