Bulletin

There were two low C flares during the past 24 hours. The brightest flare (C1.6) was released by NOAA AR 2137 and peaked around 12:34 UT on August 10. In the next 48 hours, eruptive conditions (C flaring) are likely, especially from AR 2137, AR 2132, and from two unnumbered regions near the East limb. Over the last 24 hours, solar wind speed as observed by ACE increased from about 300 to about 420 km/s, probably under the influence of a coronal hole high speed stream. The magnitude of the Interplanetary Magnetic Field (IMF) varied between 8 and 11 nT. Over the past 24 hours, geomagnetic conditions were quiet (K Dourbes between 1 and 3; NOAA Kp between 1 and 2) except for one three-hour excursion of active conditions (K Dourbes = 4) between 18h and 21h UT on August 10. Quiet geomagnetic levels (K Dourbes < 4) are expected on August 11, 12, and 13, with possible excursions to active levels on August 13 due to the arrival of another coronal hole high speed stream.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 047, basierend auf 19 Stationen.
