Solar activity in past 24h has been low. NOAA AR 2268, close to the east limb, produced a C4.3 flare with peak at 02:53 UT. This region has potential for M-class flaring in the next 48h. The effect of the fast speed stream from a coronal hole has reduced in the past 24h. Solar wind speeds are at 400 km/s with magnetic fields intensity around 5 nT. Geomagnetic conditions have ranged from quiet to unsettled. The fast speed stream from another high latitude coronal hole may influence the Earth in the next 48h, most likely producing active geomagnetic conditions at most.
