The Sun Online and solar activity. July 27, 2014

Solar activity has been low with a couple of low level C flares from Catania group 24 (NOAA AR 2123), the strongest one peaking at 13:20 UT at C1.8 level and from NOAA AR 2125 (no Catania number) peaking at 5:51 UT at C2.5 level. Solar activity is expected to remain low over the next days with only a
slight chance for an M flare. A CME was seen departing the west limb (visible in SOHO/LASCO C2 from
around 15:12UT), but it is not Earth directed.After reaching a maximum of over 420 km/s at the start of the reporting period solar wind speed dropped to under 340 km/s and is currently back at around 370 km/s. Total magnetic field dropped from over 8nT to around 5nT with Bz variable within that magnitude but currently mainly positive around 3nT. Geomagnetic conditions have been quiet (NOAA Kp 1-2, local K Dourbes 0-3) with an isolated local unsettled period between 18 and 21 UT. Solar wind parameters are expected to remain nominal but to increase later due to the influence of a coronal hole high speed stream. Geomagnetic conditions are expected to be quiet first and later quiet to unsettled.
