The new region on disc, NOAA region 2894, produced the strongest flare of the period, a C2.3 flare peaking at 21:57UT. As it is rotating further onto the disc it now shows to be bipolar with some small trailing spots. The spots of NOAA region 2891 have shrunk significantly and seem about to disappear completely, while the region did produce a low C flare in the period. NOAA region 2893 remained quiet. It remains likely that some C flaring will occur in the coming 24 hours.

No Earth directed CMEs have been recorded in coronagraph data.

The more than 10MeV proton flux was at background values and is expected to remain at background values. The greater than 2 MeV electron flux reached briefly above the 1000 pfu threshold during the diurnal maximum and is likely to do so again today. The 24h electron fluence remained at normal levels but is expected to be at normal to moderate or even high levels with the continued elevated Solar wind conditions.

Solar wind speed remained elevated in the wake of the CME. It decreased from 600km/s at the start of the period to around 500km/s, but saw again a peak of over 600km/s this morning. The interplanetary magnetic field showed a similar pattern, decreasing from 10nT to under 5nT but with again a peak over 10nT around midnight. The magnetic field orientation was variable and without sustained periods of any strong southward component. Solar wind conditions are expected to first continue to decrease but they may become slightly elevated again from late tomorrow November 7 or early November 8 due to possible weak high speed stream influences related to a small positive polarity equatorial coronal hole.

Geomagnetic conditions were quiet to active (NOAA Kp 3-4 and local K Dourbes 2-4). Geomagnetic conditions are expected to be mostly quiet to unsettled over the next days.
