The Sun Online and solar activity. July 28, 2014

There are 8 relatively small sunspot groups visible. NOAA 2127, still close to the southeast limb, and NOAA 2126 produced each one C1.2 flare (peaking resp. at 14:18UT yesterday and at 11:45UT today). Both regions seem to have some mixed magnetic polarity.  No Earth-directed CMEs were observed. Some 10-20 degrees long filaments are observed in the NE, SE and NW solar quadrant, as well as in NOAA 2121.  There’s a chance on further C-class flaring, in particular from NOAA 2127
and 2126. An eruption of one of the filaments is possible.
A disturbance was observed in ACE solar wind data starting shortly after 03:00UT. Over the next four hours, wind speed gradually increased from 350 to 430 km/s, while Bz varied between +11 and -8 nT, being mostly positive near the end of the period. The geomagnetic field was unsettled to locally active in response to this disturbance. Quiet to unsettled geomagnetic conditions are expected, with locally an
active period possible.
