Bülletään

NOAA 2415, currently the most complex sunspot region on the solar disk, produced the strongest flare of the period (C3.0 flare peaking at 02:24UT). The other 4 regions were mostly quiet, with NOAA 2414 producing a single C1 flare. No earth-directed coronal mass ejections have been observed.

More C-class flares are expected, with a small chance on an M-class flare from NOAA 2415.

Solar wind speed gradually declined from values near 520 km/s to its current 470 km/s. Bz oscillated between -6 and +6 nT, with the interplanetary magnetic field pointing away from the Sun. Quiet to unsettled conditions were observed, with a single active episode at Dourbes (15:00UT). The trailing transequatorial extension of a wide northern coronal hole is transiting the central meridian.

Quiet to unsettled geomagnetic conditions are expected, with a chance on an active episode. Minor geomagnetic storming is expected on 18 and 19 September.
