Solar activity has been low over the past 24 hours. The largest flare was a C3.6 class flare. NOAA Active Region (AR) 2458 (Cao Beta) has produced most of the activity, including the C3.6 flare peaking at 08:10 UT. Both ARs 2458 and 2459 have shown some evidence of flux emergence and have the potential to produce more activity. ARs 2457 and 2461 have rotated onto the West limb. The above-mentioned C3.6 flare has shown evidence of an associated EUV wave and coronal dimmings, indicating an associated eruption. There are currently no Coronagraph observations to verify this, but the source region is in a location likely to produce an Earth directed CME. A PRESTO will be issued once/if the presence of an associated CME is verified. The solar wind speed has fluctuated around 500 km /s over the past 24 hours. The total magnetic field has remained around 5 nT over the past 24 hours. The Bz component has oscillated between +5 and -5 nT. Geomagnetic conditions were quiet to moderate over the past 24 hours (NOAA Kp 1-3, local K Dourbes 1-3). There is currently a large positive polar coronal hole and smaller positive transient coronal hole at lower latitudes on the Sun which are probably the source of enhanced solar wind conditions at the Earth, the continued presence of these regions in the Western hemisphere may enhance solar wind conditions at the Earth over the next day. Geomagnetic conditions are expected to be quiet to unsettled.
