Over the past 24 hours solar activity has been low. The largest flare was a B2.1 class flare (Although, a similar magnitude flare was occurring at time of writing). Active Region (AR) 2738 (Mcintosh class:Cho; Mag. type:Beta) has produced all the flaring activity, the region has shown some evidence of flux emergence and cancellation in HMI magnetogram observations, this may increase flaring activity. No significant filament channels have been seen on the solar disk. However, there is evidence of a back-sided filament eruption (STEREO-A Observations) near the south polar coronal hole occurring around 14:30 UT. The eruption can be seen as a small Coronal Mass Ejection (CME) emerging to the south-east of the solar disk, in LASCO observations. The eruption is not expected to interact with the Earth system. No Earth directed CMEs have been detected. There are no significant low latitude coronal holes on the solar disk. 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 reasonable chance of a C-class flare from AR 2738.

The solar wind speed has fluctuated between 410 and 460 km/s over the past 24 hours. The total magnetic field strength has fluctuated around 5 nT. The Bz component has fluctuated around 0 nT, ranging between -5 and +4 nT. Geomagnetic conditions ranged between Kp index 2-3 (NOAA) and local K index 1-3 (Dourbes) over the past 24 hours. Geomagnetic conditions are expected to be quiet.
