Bülletään

There are currently 4 small sunspot groups visible on the solar disk. NOAA 2389, still close to the southeast limb, seems to show some mixed magnetic polarities. It was the source of the sole C-class flare of the period (C1.0 at 03:12UT). No earth-directed coronal mass ejections (CMEs) were observed.

There's a chance on another isolated C-class flare.

Solar wind speed gradually declined from values between 500 and 550 km/s to its current 400 km/s. Bz fluctuated between -8 and +6 nT. Active episodes were observed between 17:00-21:00UT. A small equatorial positive coronal hole is transiting the central meridian.

Mostly quiet to unsettled geomagnetic conditions are expected, with a chance on an active period in response to the high speed stream from the positive CH on the northern hemisphere.
