Bulletin
We expect continued C-class flaring activity from several active regions on the disc. A new -yet unnumbered- active region has crossed the solar NE limb and might boost solar activity further in the coming days. Quiet geomagnetic conditions are expected in the coming 3 days: there are no high speed wind streams expected from coronal holes, nor are there any new CMEs on the way to the Earth.
Today's estimated international sunspot number (ISN): 083, based on 16 stations.Solar indices for 20 Aug 2014
