Bulletin

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 the B class level. There is currently a small patchy coronal hole near the central meridian. Solar activity is expected to remain at low levels for the next 24 hours.

The greater than 10 MeV proton flux was at nominal values.

Over the past 24 hours, the solar wind speed decreased from 600 km/s to 500 km/s. The total magnetic field strength has fluctuated between 4 nT and 8 nT. The Bz component fluctuated around 0 nT, ranging between -5 and +5 nT. Geomagnetic conditions ranged between Kp index 2-3 (NOAA) and local K index 1-4 (Dourbes) over the past 24 hours. Geomagnetic conditions were enhanced due to a high speed stream (HSS) from a small low latitude positive polarity Coronal Hole (now at the West limb). Geomagnetic conditions should continue to decline, but may experience the occasional fluctuation.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 000, basierend auf 07 Stationen.
