Bülletään

The past 24 hours were mostly quiet, with 2 moderate C-class flares. The first one, a C1.1 event, took place in NOAA AR 1776, on June 19, 1709 UT (peak time), and was associated with dimmings. A faint CME is associated with this event and is first observed by LASCO C2 around 18:48 UT. It is going essentially southward, at slow project speed (~300 km/s). We do not expect much geomagnetic effect, and if any not before early June 24. The second one (C1.9) occurred in Catania region 10 (S15E89), on June 20, 0920 UT (peak time). Geomagnetic activity is expected to be active by the end of June 21 - beginning of June 22, as a coronal hole becomes geoeffective. Current conditions are quiet. ACE observations show some minor excursions of the Bz component of the interplanetary magnetic field down to -5nT, associated with a small shock-like structure observed late on June 19.
