Solar X ray flux remained below B level throughout the period. There are no active regions on disk and X-ray flux is expected to remain at background levels.

No new Earth-directed CME's were detected in coronagraph images. A negative polarity coronal hole is currently transiting the central meridian and will influence Solar wind from October 30 onwards.

Solar high energy proton fluxes were at background levels and are expected to remain so. 2 MeV electron fluxes remain enhanced associated to the ongoing high speed stream.

Solar wind speed increased again at the start of the period to around 670 km/s before starting again a slow gradual decline to current values of now 550 km/s. Total magnetic field decayed from around 6nT to around 4nT. Bz was overall variable over the period and the phi angle was firmly in the positive sector. Solar wind is expected to further decline slowly over the next 24-48 hours as the high speed stream subsides. Later by the second half of October 29 we may see some transients related to the October 25 CME reported yesterday, then followed by a new Solar wind speed enhancement due to the negative polarity coronal hole currently transiting the central meridian.

Geomagnetic conditions were mostly quiet to active (NOAA Kp and local K Dourbes 2-4) with isolated minor geomagnetic storm periods locally (K Dourbes 5). Active geomagnetic conditions are still likely over the next 12 hours before returning to unsettled conditions. Then some new active periods are possible by late October 29 associated to the possible ICME passage.
