Bulletin

Solar activity has been mostly quiet except for Catania group 22 (NOAA AR 2121) which did produce another C2 flare peaking at 7:02 UT. The background X-ray flux rose slightly to around the B3 level. Similar conditions (essentially quiet but with a significant chance for an occasional low level C flare) are expected to continue with an increasing C flare probability as some returning active regions are turning into view over the next days. These will eventually also raise a slight chance for M level flares. No Earth directed CME's have been observed. After reaching maxima of just over 400km/s at the start of the reporting period, solar wind speed decreased to a minimum of about 310 km/s and later increased again gradually to values presently about 360 km/s. The total magnetic field varied essentially in the 2 to 6.5 nT range with Bz also variable in the +-6nT range. Geomagnetic conditions were quiet to unsettled (local K Dourbes 2-3 and NOAA Kp 1-3). Similar solar wind conditions as well as geomagnetic conditions (quiet to unsettled) are expected to continue over the next days.

Dnešní odhadovaný mezinárodní počet slunečních skvrn (ISN): 051, na základě 21 stanic.
