NOAA AR 980 has a relatively simple beta magnetic field configuration and is not expected to produce any more significant flaring activity. A new active region is currently crossing the Eastern solar limb (best seen in STEREO-B data). Geomagnetic conditions will remain quite until the arrival of the high wind speed, expected by Sunday, of the recurrent coronal hole that is now near central meridian. TODAY'S ESTIMATED ISN : 008, BASED ON 05 STATIONS.
