Bulletin

The only numbered sunspot group (Catania group 29, NOAA region 2758) presently observed on the visible side of the solar disc is decaying. NOAA AR 2758 was the source of one B-class flare reported during last 24 hours. The B2.3 flare (peak at the 05:56 UT this morning) was associated with the coronal dimming and faint EIT wave, on-disc signatures of the CME. However, the presently available coronagraph observations do not show possibly associated CME, more will be reported once the coronagraph data become available. During last 24 hours there were no Earth directed CMEs observed and the solar protons remained at the background level.

Earth is presently within the slow solar wind with the speed of about 300 km/s and the interplanetary magnetic field magnitude is 2 nT. The geomagnetic conditions are presently quiet to unsettled and we expect them to stay so in the coming hours.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 000, sur la base de 13 stations.
