Bulletin

Over the past 24 hours solar activity has been low. No significant flares have been recorded. Active Region (AR) 2655 (Mcintosh class:Dro; Mag. type:Beta) has exhibited significant flux emergence in HMI magnetogram observations producing multiple B-class flares. No Earth directed Coronal Mass Ejections (CMEs) have been detected in coronagraph observations. The greater than 10MeV proton flux remained at background levels over the past 24 hours. Solar activity is expected to remain low over the next 24 hours with a small probability of C-class flares. The solar wind speed has been slowly decreasing from around 420 to 330 km/s over the past 24 hours. The total magnetic field strength has fluctuated between 7 nT and 8 nT. The Bz component was largely positive, varying between -1 nT and 8 nT. Geomagnetic conditions ranged between Kp index 0-2 (NOAA) and local K index 0-2 (Dourbes) over the past 24 hours. Over the next 24 hours Geomagnetic conditions are expected to be quiet to unsettled.

Today's estimated international sunspot number (ISN): 027, based on 14 stations.
