NOAA AR 2671 produced only 1 C-class flare in past 24 h (C1.1 peak at 13:52 UT on August 15), associated with a CME directed to the west that is not expected to affect the Earth. This region has a beta magnetic field configuration and it is still evolving, more C-class flares can be expected (and less likely M-class flares).
No Earth directed Coronal Mass Ejections (CMEs) have been detected. Solar protons have remained at background levels over the past 24 hours.
Geomagnetic conditions have been quiet (K and Kp 1 to 2). Solar wind speed is at 370 km/s with interplanetary magnetic field intensity of 5 nT. The fast solar wind from a coronal hole is expected to arrive within 24 h, producing K values up to 5 (with possible isolated periods of K values up to 6).
Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 029, sur la base de 20 stations.
