Goes X-ray flux background is now at A5 levels. No flaring activity above C level is expected within the next 48 hours. Geomagnetic activity was very low. The solar wind speed measured by the ACE satellite is below 500 km/s as the Earth slowly quits the high speed stream coming from the southern coronal hole. Quiet conditions are expected for the next 48 hours. TODAY'S ESTIMATED ISN : 024, BASED ON 02 STATIONS.
