Bulletin

The solar activity has been quiet over the past 24 hours. The sun is currently spotless and the X-ray flux remained below B-level. Solar activity is expected to remain at low levels for the next 24 hours.

No Earth directed coronal mass ejections (CME) were observed over the last 24 hours in the available coronagraph imagery. The greater than 10 MeV proton flux remained at background levels over the past 24 hours and is expected to remain at low levels.

The solar wind speed was stable with values around 400 km/s (ACE). The total interplanetary magnetic field remained below 6 nT , the Bz component varied between -4 nT and +4 nT. The solar wind parameters might show some small enhancement for the coming days due to the very mild effect of the South pole coronal hole wind streams.

Quiet to unsettle geomagnetic conditions were observed with the Kp index (NOAA) ranging between 0-2 and the local K index (Dourbes) ranging between 0-3 over the past 24 hours.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 000, basierend auf 28 Stationen.
