Bulletin

No significant flares were recorded, with NOAA 2373 and 2384 producing a single B-class flare each. The other regions were quiet. A compact region (Catania 11) about 20 degrees to the west of NOAA 2381 is developing quickly and shows some mixed magnetic polarities. No obvious Earth-directed coronal mass ejections (CME) were observed. A 140 degrees wide CME first observed by LASCO/C2 at 00:48UT seems to have been the result of a series of very slow eruptions along a lengthy filament channel near -45 degrees latitude. The bulk of the ejected material is directed well south of the ecliptic.

There remains a good chance on a C-class flare.

Solar wind speed varied between 340 and 400 km/s, with Bz fluctuating between -4 and +3 nT. Quiet to unsettled geomagnetic conditions were observed and are expected to persist.

Active geomagnetic conditions are possible late 10 or on 11 July under the effects of the equatorial coronal hole wind stream. A minor storming episode is not excluded.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 117, gebaseerd op 21 stations.
