The Sun Online and solar activity. November 20, 2013

Solar activity has been rather moderate during the past 24 hours, with only weak C class flares since the X class event of yesterday. The 10 MeV proton flux rose sharply soon after the flare but did not cross the event threshold. Active conditions are expected for the next 48 hours, with still a risk for an isolated M class flare from NOAA AR 1893, and to a lesser extent NOAA AR 1897. We expect quiet geomagnetic conditions to prevail for the next 48 hours. The CME associated with the X1.0 flare of Nov. 19 is not expected to be geoeffective. Current ACE measurements reveal quiet interplanetary conditions.
