Over the past 24 hours solar activity has been low. The largest flare was a C2.2 class flare. Active Region (AR) 2583 (Macintosh class:Dao; Mag. type:Beta) has been most active, producing several C class flares, including the C2.2 class flare, which peaked at 03:34 UT. All other ARs have shown low levels of activity. AR 2583 and 2580 (Hrx; Alpha) have shown evidence of flux emergence, separation and cancellation in HMI magnetogram observations, this may increase flaring activity. However, the region is approaching the West solar limb. A filament channel is currently located near disk center, but appears stable. Solar protons have remained at background levels over the past 24 hours. Solar activity is expected to remain low over the next 24 hours with a high probability of C-class flares and a low probability of M-class flares. The solar wind speed has fluctuated between 380 and 320 km/s over the past 24 hours. The total magnetic field strength has remained around 4 nT throughout yesterday and this morning, however it jumped toward 10 nT in the last hour. The Bz component was largely positive, fluctuating between -5 and +10 nT. Geomagnetic conditions ranged between Kp index 0-2 (NOAA) and local K index 0-3 (Dourbes) over the past 24 hours. A small trans- equatorial coronal hole located at central latitudes, N01W50, is expected to enhance solar wind speeds at Earth due to its associated high-speed stream (HSS). This may enhance geomagnetic activity. A large positive polarity Northern polar coronal hole located near central longitudes extending toward low latitudes is expected to enhance solar wind speeds in coming days. Geomagnetic activity is expected to be slightly enhanced later today and again later in the week.
