Bülletään

The solar activity has been at very low levels over the past 24 hours. The Sun is currently spotless and the X-ray flux remains below B-level. However, a compact bright structure, located at low-latitude near the central meridian, has shown some evidence of activity. There is currently a low-latitude positive-polarity patchy coronal hole located in the Western Hemisphere. Solar activity is expected to remain at low levels for the next 24 hours.

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 speed has decreased from around 350 to 330 km/s over the past 24 hours. The total magnetic field strength has fluctuated between 1 nT and 4 nT. The Bz component fluctuated around 0 nT, ranging between -3 and +3 nT. Geomagnetic conditions ranged between Kp index 0-1 (NOAA) and local K index 0-2 (Dourbes) over the past 24 hours.

Geomagnetic conditions are expected to increase later today / tomorrow, due to the arrival of the high speed stream (HSS) / CIR related to a patchy low-latitude positive polarity Coronal Hole that passed the central meridian a couple of days ago.
