Bulletin

Seven C-class flares were observed, the strongest a C4.4 flare from NOAA 2449 peaking at 18:11UT. This active region seems to have gained somewhat in sunspot area and magnetic complexity. The other flare producing sunspot groups were NOAA 2446, NOAA 2448, and an unnumbered region south of NOAA 2449. No earth-directed coronal mass ejections have been observed.

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

Major geomagnetic storming has been observed at the planetary level (Kp = 6) during the 03-06UT and 06-09UT interval. At Dourbes, minor storming was observed between 04 and 08UT. This geomagnetic disturbance resulted from the passage of the 04 November coronal mass ejection (CME). A shock was observed by ACE near 17:35UT, with solar wind speed jumping from about 440 km/s to 560 km/s, then gradually increasing until maximum speeds near 710 km/s were reached around 03:00UT. Bz was initially wildly oscillating between -16 and +18 nT before turning to steady negative values near -11 nT starting around 02:00UT. The current solar wind speed is near 550 km/s, with Bz still at negative but less intense values around -5 nT.

For the next few days, active to minor storming episodes remain possible first in response to the waning effects from the CME passage, and then, starting late on 08 November, in response to the arrival of the co-rotating interaction region and high speed stream associated with the northern coronal hole.
