Bulletin

The strongest flare, out of three C-class flares reported during last 24 hours, was the C8.9 flare (peaked at 00:34 UT) on August 09. The flare originated from the NOAA AR 2574 situated close to the East solar limb, and was associated with narrow and slow CME. In the coming hours we expect C-class flares and possibly, but not very probably, an isolated M-class flare. No Earth directed CMEs were observed in the last 24 hours.

The Earth is presently inside the fast solar wind with the speed of about 650 km/s, and the interplanetary magnetic filed magnitude amounts 7 nT. At about 09:00 UT this morning the solar wind speed started to increase, simultaneously with the fluctuations of the Bz component of the interplanetary magnetic field. This indicates arrival of the fast flow, probably associated with the large northern polar coronal hole with the extent to the low latitudes (which reached central meridian on August 06). The fast flow could induce active to minor storm geomagnetic conditions in the coming hours.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 073, gebaseerd op 24 stations.
