Bulletin

Over the past 24 hours solar activity has been very low. No significant flares have been recorded. There are currently two Active Regions (ARs) near disk centre, and a new AR (2600) that emerged over the east limb. All appear stable in HMI magnetogram observations. There is a small northern polar coronal hole that is not expected to increase solar wind speeds at Earth. Although the Sun has been quiet there is a reasonable chance of C-class flares over the next 24 hours. The solar wind speed has fluctuated between 425 and 475 km/s over the past 24 hours. The total magnetic field strength has fluctuated between 4 nT and 7 nT. The Bz component fluctuated between -4 and +5 nT, but remained mainly positive. Geomagnetic conditions ranged between Kp index 0-3 (NOAA) and local K index 1-3 (Dourbes) over the past 24 hours. There is currently a positive polarity Northern polar coronal hole which shouldn't affect the Earth. Geomagnetic conditions are expected to be quiet to unsettled.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 061, basierend auf 08 Stationen.
