Bülletään

The strongest flare of the past 24 hours was the C1.7 flare peaking at 07:26 UT today in the Catania sunspot group 21 (no NOAA number yet) that has just crossed the east limb. More C-class flares are expected in this group, with a small chance for an M-class flare. The solar wind speed is currently around 550 km/s, probably indicating the imminent arrival of a fast stream from the trans-equatorial coronal hole. The interplanetary magnetic field (IMF) is currently around 7 nT. Yesterday evening, in the interaction region between the fast stream and the preceding slow flow, the IMF Bz component stayed negative (down to -10 nT) for around 3 hours, so active geomagnetic conditions (K = 4) were reported by IZMIRAN and NOAA. (Intervals of K = 5 reported this morning by Dourbes are most probably spurious.) We expect active to minor storm conditions in the coming hours as the Earth will be going through the fast solar wind stream.
