Bülletään

About a dozen C-class flares occurred during the past 24 hours, originating from Catania sunspot regions 79, 80 and 87 (NOAA active regions 2360, 2361 and 2367). The largest flare was a C8.3 flare peaking at 14:37 UT on June 11, coming from Catania region 87. Catania region 83 has developed to a beta-gamma region. More C-class flares are expected and quite likely also an isolated M-class flare. Two rather narrow CMEs (first measurements at 11:00 UT and 14:48 UT on June 11 in LASCO/C2) of less than 100 degrees angular width are propagating to the East without any expected geoeffectiveness.

High speed stream effects on Earth are reducing. Solar wind speed has decreased from 600 to 450 km/s, while the magnetic field magnetic was maximally at 5 nT. Geomagnetic conditions are quiet to unsettled (K= 1 to 3), with a single time slot of active levels (K=4) at Dourbes. Geomagnetic conditions might enhance in case of arrival of the June 9 CME, potentially expected today. The arrival of a new high speed stream is expected on June 14 or 15, emanating from a negative polarity equatorial coronal hole.
