Bulletin

Over the past 24 hours solar activity has been very low. No significant flares have been recorded. Active Region (AR) 2670 (Mcintosh class:Hsx; Mag. type:Alpha) has been quiet, but has shown some evidence of flux emergence and cancellation in HMI magnetogram observations, which may result in flaring activity. No Earth directed Coronal Mass Ejections (CMEs) have been detected. 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 low probability of C-class flares. The solar wind speed has decreased from around 520 to 450 km/s over the past 24 hours. The total magnetic field strength has remained around 3 nT. The Bz component fluctuated around 0 nT but was mainly positive, ranging between -5 and +3 nT. Geomagnetic conditions ranged between Kp index 0-2 (NOAA) and local K index 0-3 (Dourbes) over the past 24 hours. Geomagnetic conditions are expected to be quiet.

Today's estimated international sunspot number (ISN): 012, based on 15 stations.
