Bülletään

The solar activity has been at very low levels over the past 24 hours. A new small bipolar sunspot group (Catania sunspot group 23) is visible on the disc close to the East limb. No significant activity coming from this new spot has been recorded and the X-ray flux remained below B-level. Solar activity is expected to remain at low levels with a small chance of a C-class flare.

No earth-directed coronal mass ejections (CMEs) have been observed in the available coronagraphic imagery. The greater than 10 MeV proton flux was at nominal values.

The solar wind parameters have slowly returned to nominal values: The total magnetic field is now fluctuating around 5 nT, the solar wind speed remains below 350 km/s, and the southern component of the magnetic filed is positive. The solar wind parameters are expected to remain at the nominal levels within the next 24 hours. A northern extension of the southern polar coronal hole (with negative polarity) stretching all the way to about 10 degree latitude has reached the central meridian. The effect of the coronal hole in the solar wind measurement at L1 is not expected earlier than in 3-4 days from now.

Quiet geomagnetic conditions were observed over the past 24 hours, and is expected to remain so for the next period.
