Bülletään

There are currently 2 sunspot groups visible on the solar disk. NOAA 2389 shows some mixed magnetic polarities. It was the source of two C2 flares, both associated with narrow but not-earth directed coronal mass ejections. NOAA 2390 is growing, but still flare silent. No other C-class flares or earth-directed coronal mass ejections (CMEs) were observed.

There's a chance on further low-level C-class flaring.

Solar wind speed varied mostly between 400 and 450 km/s, while Bz fluctuated between -6 and +7 nT. Quiet to unsettled geomagnetic conditions were observed, with locally at Dourbes an active episode at 09:00UT. A small equatorial positive coronal hole has transited the central meridian.

Mostly quiet to unsettled geomagnetic conditions are expected, with a chance on an active period.
