Bulletin

Solar X-ray flux was below B level throughout the period. The only region on disc (Catania group 29, NOAA region 2758) decayed during the period. X-ray flux is expected to remain below C level.

No Earth directed CMEs have been observed in coronagraph data.

Proton flux levels were at background values and are expected to remain so.

Solar wind parameters displayed nominal slow Solar wind conditions. Velocity was between 310-380 km/s. Total magnetic field was around a nominal 5nT with a variable Bz. The phi angle was mostly in the negative sector. Solar wind conditions may become somewhat enhanced by the influence of small extensions of the Southern negative polarity polar coronal hole, though there is significant uncertain if this will actually set through.

Geomagnetic conditions were quiet to unsettled (NOAA Kp 1-2, local K Dourbes 1-3). Essentially quiet to unsettled conditions are expected over the next days with possible active periods in case Solar wind becomes enhanced under the influence of the Southern polar coronal hole extensions.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 000, sur la base de 06 stations.
