Bulletin

NOAA AR 1726 remains very dynamic. As it rotates over the solar west limb in the coming 24h, it could still produce a large flare before disappearing out of Earth view. The solar wind speed is still increasing as a result of the influence of a recurrent coronal hole. Nevertheless we expect that most of the resulting geomagnetic activity has passed. Hence we predict quiet geomagnetic conditions. A halo CME was observed by SOHO/LASCO first seen in the C2 field of view at April 23 00:48. However as this CME was determined to be back sided, we do not expect geomagnetic consequences.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 077, basierend auf 17 Stationen.
