Bulletin

Over the past 24 hours solar activity has been very low. No significant flares have been recorded. Active Region AR 2598 (Mcintosh class:Dai; Mag. type:Beta) has been most active producing B-class flares, but shows evidence of flux emergence in HMI magnetogram observations, which may result in increased flaring activity around the C-class level over the next 24 hours. The solar wind speed has fluctuated between 400 and 475 km/s over the past 24 hours. The total magnetic field strength has fluctuated between 3 nT and 7 nT. The Bz component fluctuated between -5 and +5 nT, but remained mainly positive. Geomagnetic conditions ranged between Kp index 1-4 (NOAA) and local K index 1-3 (Dourbes) over the past 24 hours. There is currently a small positive polarity Northern polar coronal hole which shouldn't affect the Earth.

Today's estimated international sunspot number (ISN): 066, based on 13 stations.
