Bulletin

The three currently visible sunspot groups have been quiet during the last 24 hours. Only NOAA 2415 is showing some magnetic mixing in its leading portion. No significant flaring has been observed since late on 11 September. No earth-directed coronal mass ejections have been observed.

Mostly quiet flaring conditions are expected, with a small chance on a C-class flare.

Solar wind speed declined from its initial 480 km/s to about 400 km/s around 07:00UT this morning, then rising to its current 500 km/s probably in response to the arrival of the high speed stream (HSS) of the northern coronal hole's extension. Since about 18:00UT, Bz has been oscillating between mostly -9 and +7 nT, with the interplanetary magnetic field pointing away from the Sun. Quiet to active geomagnetic conditions were observed. A wide coronal hole (CH) is transiting the central meridian (CM). Its trailing transequatorial extension is expected to start its CM transit on 15 September.

Mostly active geomagnetic conditions are expected over the next few days, with possible episodes of minor storming on 14 and 15 September, and minor to moderate storming on 18 and 19 September.
