Bülletään

Solar X-ray flux remained below B level. With no regions on disk chances for C-class flaring are very low.

No Earth directed CMEs have been observed in coronagraph images.

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

Solar wind speed declined over the period to be mainly in the 400-420 km/s range with lately a further decline to 390 km/s. Total magnetic field saw another period of slight enhancement reaching close to 10nT and now back at around 6nT. Bz was mostly positive and the phi angle was in the negative sector.. Slightly enhanced conditions are expected to continue over the next days related to the Southern coronal hole regions.

Geomagnetic conditions were quiet to unsettled (both local K Dourbes and NOAA Kp 0-3) and are expected to remain so over the next days.

Tänane hinnanguline rahvusvaheline päikeselaikude arv (ISN): 000, põhineb 17 jaamadel.
