Bulletin

Four sunspot groups are reported by Catania today. The strongest flare during the last 24 hours was the C4.7 flare peaking at 01:52 UT in the NOAA AR 2303 that just passed behind the north-west solar limb (and therefore does not have a Catania number anymore). We expect flaring activity on the low C-level in the next 48 hours. A partial halo CME was first seen in the SOHO/LASCO C2 field of view at 18:24 UT on March 29. It had the angular width of around 190 degrees and the plane-of-the-sky projected speed of around 700 km/s. SDO/AIA data indicate that this was a far-side event. It will therefore not arrive at the Earth and have no geomagnetic consequences. The Earth is currently inside a slow (around 340 km/s) solar wind flow with average (around 6 nT) interplanetary magnetic field magnitude. The geomagnetic conditions are quiet and are expected to remain so until the arrival of a fast flow from a low-latitude extension of the southern polar coronal hole later today or early tomorrow. Geomagnetic disturbance up to the minor storm level is expected.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 043, basierend auf 17 Stationen.
