公告

There are currently 9 sunspot groups visible. Only 2 low-level C-class flares were observed over the last 24 hours, both having NOAA 2157 as their source. This active region still has a delta in its main trailing spot. NOAA 2158 seems to have lost its delta structure, and has not produced any flares. The other sunspot groups are quiet. Two active regions are approaching the east limb. The greater than 10 MeV proton flux is still slightly enhanced and is currently at 1 pfu. It continues its slow decline. C-class flares are expected, with a chance on another M-class event. Solar wind speed was mostly between 350 and 400 km/s, with Bz varying between +6 and -5 nT. Geomagnetic conditions were quiet to unsettled. Quiet to unsettled geomagnetic conditions are expected on 10 and most of 11 September, possibly modulated by the high speed stream from a coronal hole that passed the central meridian on 5 September, and a glancing blow from the 6 September CME. Locally, an isolated active period is possible. Late on 11 and on 12 September, the impact of the halo CME related to the M4.5 flare from 9 September may result in active conditions and possibly a brief period of minor geomagnetic storming.
