Bulletin

A new active region (AR) NOAA 2550 has developed rapidly during the past few hours. Solar flaring activity was restricted to a C1.4 flare (peaking at 7:37 UT, originating from NOAA AR 2550) and several B-class flares. The C1.4 flare was associated with a type II burst, observed at Humain. No Earth directed coronal mass ejections (CMEs) were observed.

The probability for a C-class flare is increasing, with mainly NOAA AR 2550 as source candidate. The Earth is currently under the influence of a coronal hole (CH) high speed stream (HSS). Solar wind speed increased from 450 km/s, reaching a maximum of 600 km/s and is currently around 500 km/s. Bz ranged from -5 and +5 nT, with a maximum magnitude of the interplanetary magnetic field (IMF) of 8 nT. The IMF was directed towards the Sun. Quiet (K=0-2) to unsettled (K=3) conditions were registered at the local level (Dourbes). Some episodes with active conditions are expected over the next 24 hours.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 047, sur la base de 10 stations.
