Bulletin

No C- or M-class flares have been recorded during the period. NOAA 2445 rounded the northwest limb, while NOAA 2443 continued its decay and magnetic simplification. An active region is rounding the southeast limb, raising the x-ray background flux but so far without significant flaring activity. A filament near the equator at 50 degrees west erupted between 15:00 and 16:00UT. No earth-directed coronal mass ejections (CMEs) were observed.

C-class flares are expected, with a chance on an isolated M-class flare.

Earth was still under the waning influence of the high speed stream (HSS) of the equatorial coronal hole (CH). Solar wind speed showed a declining trend varying between 570 km/s and its current 460 km/s. Bz varied mostly between -4 and +3 nT, being mostly negative. The interplanetary magnetic field was directed away from the Sun. Quiet to active geomagnetic conditions were observed. A wide positive northern coronal hole (CH) reaching down to +10 degrees latitude has started transiting the central meridian early on 06 November.

Expected geomagnetic conditions range from quiet to active, with minor storming possible on 07 November in response to the expected arrival of the 04 November CME. A major storming episode cannot be excluded. Starting late on 08 November, active to minor storming is possible in response to the arrival of the co-rotating interaction region and HSS associated with the northern CH.
