Bülletään

Over the past 24 hours solar activity has been low. There are currently tree active regions on the visible discs, but only Catania group 47 (NOAA region 2674) produced small C-class flare. We expect the activity to remain low with a probability of few sporadic C-class flare.

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

A minor geomagnetic storm was observed on August, 29 with a peaking around 21:00 UT. This may be due to an Interplanetary CME that provoked a shock onto the Solar Wind on August, 29 around 16:00 UT. Currently, the geomagnetic conditions are returning to quiet with Kp (NOAA) and local K (Dourbes) indexes ranging between 1-2. A minor to moderated storm (K between 5 and 6) is expected on August, 31 when the fast solar wind coming from the large coronal hole crossing the central meridian on August 29 will reach Earth.
