INFO FROM SIDC - RWC BELGIUM 2015 Apr 15 12:37:00 UTC
Only low C-class flares were reported in the past 24 hours. NOAA AR 2321 has currently beta-gamma configuration of its photospheric magnetic field. We expect C-class flares and possibly also an isolated M-class flare, in particular from NOAA ARs 2321, 2324, and 2325. No Earth directed CMEs were observed during last 24 hours. The solar wind speed increased to about 550 km/s and the interplanetary magnetic field magnitude is currently around 14 nT, probably indicating the arrival of the fast flow from the equator ward extension of the southern polar coronal hole. The Bz component of the interplanetary magnetic filed had few long intervals of negative value (about -10nT). Consequently, the K index have now reached value of 5, as reported by IZMIRAN and NOAA. The partial halo CME of April 12 might arrive at the Earth in the late evening of the April 15 or early morning of April 16. We expect minor storm to active geomagnetic conditions to continue in the coming hours.
