PRESTO FROM SIDC - RWC BELGIUM Thu Mar 18 2010, 1229 UT

The current low solar activity is expected to extend over the next 3-day period, with possible occasional C flares. Due to the moderate speed of the solar wind, the geomagnetic field is expected to be quiet to unsettled for the rest of March 18 (UT), and then to become mostly quiet over the next few days.
