Radiation is moderate to low, fluctuating at a flux of about 500. Spaceweather.com: SOLAR ACTIVITY: Twisted "delta-class" magnetic fields have formed above two sunspots: 9957 and 9961. Such fields harbor energy for powerful eruptions; forecasters estimate a 20% chance of X-class solar flares during the next 24 hours. Meanwhile, an impressive series of coronal mass ejections (pictured right) billowed away from the Sun during the early hours of May 22nd. Stay tuned for details. NOAA SEC: Solar Activity Forecast: Solar activity is expected to be moderate during the next three days. The most likely sources for energetic flare activity are 9957 and 9961, although 9960 could contribute an isolated M-class event. There is a slight chance for an X-class flare or proton producing event. No COMM this shift.
