Bulletin

Over the past 24 hours solar activity has been very low. No significant flares have been recorded. All Active Regions (AR) have shown little activity. AR 2598 (Mcintosh class:Dai; Mag. type:Beta) has shown 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. No Earth directed CMEs have been observed. The solar wind speed has slowly declined from around 450 to around 380 km/s over the past 24 hours. The total magnetic field strength has remained around 5 nT. The Bz component fluctuated between -5 and +5 nT, but remained mainly negative. Geomagnetic conditions ranged between Kp index 1-2 (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): 072, based on 16 stations.
