Bulletin

NOAA AR 2529 is now a beta-gamma region and released one C flare in the past 24 hours: a C4.1 flare which peaked at 14:30 UT on April 15. More C flares (probability 75%) are expected in the next 24 hours, with a slight chance (probability 15%) for an M flare, especially from AR 2529. Solar wind speed was near 360 km/s until around 04:30 UT on April 16, when it started rising till it reached a plateau of about 440 km/s around 05:30 UT. The magnitude of the Interplanetary Magnetic Field (IMF) varied between 2 and 11 nT. Over the past 24 hours, geomagnetic conditions have been quiet to unsettled (K Dourbes between 0 and 3; NOAA Kp between 1 and 3). Quiet to unsettled geomagnetic levels (K Dourbes < 4) are expected on April 16, 17 and the first half of April 18. Active to minor storm periods are possible in the second half of April 18, when a high speed stream associated with a positive coronal hole is expected to arrive.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 046, basierend auf 16 Stationen.
