The solar wind speed is steady around 450km/s with a small and mainly northward Bz. Geomagnetic conditions are expected to remain quiet, with slight potential for short term active periods due to over-expansion of a fast stream from a small coronal hole to the SW of disk centre. Solar conditions are expected to remain quiet. Old NOAA AR 0838 (Catania 86) yielded a C1.5 flare before rotating over the W limb, while of the current on-disk regions AR 0841 (Catania 89) holds the greatest potential for an isolated C-class flare.
