Bülletään

Over the past 24 hours, the solar activity remained at the low level. The magnetic configuration of Catania group 43 (NOAA region 2672) is still simplifying and has not produced any flare. A region listed as Catania group 47 is rotation from behind the East solar limb, and it shows some activity. It produced several narrow CMEs and one C3-class flare (peak-time at 0:3:00UT, August, 29). This will enhance the activity levels in the coming days.

No Earth directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraph imagery and the solar protons remains at background level.

The Earth is presently inside the slow solar wind with the speed below 400 km/s, the interplanetary magnetic field magnitude below 10 nT, and the Bz component being mainly negative around -5 nT. The fast solar wind associated with the coronal hole currently facing Earth is expected to arrive on August, 31 around noon UT time.

The geomagnetic conditions are presently very quiet with Kp (NOAA) and local K (Dourbes) indexes ranging between 1-2. The geomagnetic conditions are expected to remain low until August, 31 when the fast solar will reach Earth.
