Solar activity has been low over the past 24 hours. The largest flare was a C1.2 class flare. NOAA Active Region (AR) 2458 (Cao Beta) has produced most of the activity, including the C1.2 flare peaking at 06:28 UT this morning. AR 2458 still shows some evidence of flux emergence and has the potential to produce more activity, but will pass over the West solar limb soon. There is currently an AR approaching the East limb, which may have the potential to increase activity in the coming days. An eruption was observed off of the Southeast limb around 18:00 UT on 2015-Nov-02, but this was back-sided and unlikely to interact with the Earth. No Earth directed CMEs have been observed in the past 24 hours. Solar activity is expected to remain low. The solar wind speed has fluctuated around 425 km /s over the past 24 hours. The total magnetic field has remained at 6 nT, and the Bz component has fluctuated between +5 and -5 nT. Geomagnetic conditions ranged between quiet and moderate (NOAA Kp 1-3, local K Dourbes 0-3). A large positive polar coronal hole, with a section extending to low latitudes, is currently located near central solar longitudes, and may increase solar wind and geo- activity conditions in 3-4 days. The solar wind conditions are expected to be at background levels over the next couple of days, with a small perturbation generated by an eruption on 2015-Dec-01.
