Bulletin

NOAA AR 2740 (Catania group 16) continued to produce several flares. The largest was a C7.3 flare peaking at 13:54UT. The region continues to exhibit mixed polarity flux and is expected to remain active. Another region (NOAA AR 2741) rotated on disk from the East. Further activity is likely at a level of C-class flares.

Coronagraph images show that the CME onset(s) related to yesterdays flaring activity from region 2740 was directed sufficiently North and East of the Earth to exclude any possible Earth directed component. No other Earth directed CME's were recorded.

Solar proton flux levels were at background values and are expected to remain so.

Solar wind conditions were nominal with solar wind speed under 400 km/s and total magnetic field under 5 nT. The North-South orientation of the magnetic field was variable and the phi angle was mostly in the negative sector. Solar wind conditions are expected to become slightly enhanced by midnight under the influence of a small equatorial coronal hole.

Geomagnetic conditions were quiet to unsettled (NOAA Kp 1-2, local K Dourbes 0-3). Geomagnetic conditions are expected to become unsettled with a possibility of an isolated active period.

Dnešní odhadovaný mezinárodní počet slunečních skvrn (ISN): 027, na základě 22 stanic.
