Bulletin

Solar activity has been eruptive during the past 24 hours, featuring five C flares from NOAA AR 11731, 11738, and a new unnumbered region near N03E89. More C-level flares are expected within the next 48 hours, with a slight chance for an M flare. In the last 24 hours, the IMF has decreased further from 6 to 4 nT. Due to the influence of a coronal hole high speed stream, solar wind speeds have ranged between about 480 and 560 km/s, and currently lie around 500 km/s. Similar solar wind speeds are likely on May 8 and 9, with a probably return to lower values on May 10. Geomagnetic activity has been at quiet levels (K Dourbes between 2 and 3; NOAA Kp between 2 and 3) during the past 24 hours. Quiet geomagnetic conditions (K Dourbes < 4) are expected for May 8 to 10.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 079, basierend auf 10 Stationen.
