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

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

Since yesterday 12:30 UT, the solar wind environment remained at nominal level: The wind speed was around 300 km/s, the interplanetary magnetic field magnitude remained below 6 nT, and Bz component fluctuated between -2 and 2 nT. This morning around 01:30 UT, the solar wind conditions became enhanced due to the sector boundary crossing (from a negative to a positive sector). The wind speed is currently around 430 Km/s, and is expected to continue to increase. The interplanetary magnetic field magnitude reached 16 nT and will probably not increase much more, the Bz component is fluctuating between -12 and 10 nT being mainly negative. This sector boundary crossing announces the soon arrival of the high speed stream associated with the northern extension Coronal Hole, which has transited the central meridian on Nov 04. These enhanced solar wind conditions are expected to persist until Nov 10 while under the influence of the high speed stream associated with the coronal hole.

Geomagnetic conditions were quiet (local K Dourbes 0-2, NOAA Kp 0-1) until this morning when disturbed geomagnetic conditions were observed with minor storm at 09:00 UT due to the sector boundary crossing and the southward Bz component. The local K Dourbes first reached 3 at 06:00 UT and NOAA Kp reached 5 at 09:00 UT. The geomagnetic conditions are expected to vary between unsettled to active conditions for up to 3 days. Minor storm conditions may be observed in the coming days, especially if the wind speed increases more and the Bz component stays negative for longer periods.
