Soft proton levels are now very low (flux around 100). NOAA SEC: Solar Activity Forecast: Solar activity is expected to be low to moderate. Region 9866 continues to grow and has the potential for major flare activity. SpaceWeather.com: A lopsided full-halo coronal mass ejection raced away from the Sun on March 11 at 2306 UT. Although it was not squarely Earth-directed, the expanding cloud will probably deliver a glancing blow to our planet's magnetosphere on March 14th. BIG SUNSPOT: A large sunspot group is crossing the face of the Sun. The active region, numbered 9866, spans an area equal to five planet Earths and has a twisted magnetic field that harbors energy for X-class solar flares. No COMM this shift.

Looking at a possible double bit error in telemetry stream which could be the cause. Mike investigating. SOT(Bill): - Current solar activity is very low. - Active regions 9866 may cause problems later on in week. - CME late on March 11 was not earth-directed, but region which caused it will be coming into view later on this week, and has potential to cause problems.
