Bulletin

The solar activity is quiet as the solar disc remains spotless; no flares and no active regions have been recorded in past 24 h on the disc. The X-ray flux is expected to remain below C level.

No Earth directed Coronal Mass Ejections have been observed and the solar protons flux remained at background levels over the past 24 hours.

The Earth remained in the fast flow, the speed has decreased up to 550 km/s on Nov 9 abound 17:00 UT before unexpectedly rising again up to a current value of 700 km/s. The interplanetary magnetic field magnitude remained below 7 nT and the Bz component was fluctuating between -6 and 6 nT. The solar wind speed is expected to remain fast as long as the Earth remains in the solar wind flow associated with the high speed stream coming from the coronal hole (that has crossed the central meridian on Nov 4).

Unsettle to disturb geomagnetic conditions were observed (local K Dourbes 2-4, NOAA Kp 3-4). As long as the Earth remains in the fast solar wind flow, further minor to moderate geomagnetic storms cannot be excluded, especially if Bz component remains negative for long period of time.
