QUIET SUN:

Solar activity is low. The biggest sunspot on the Earthside of the sun, AR1783, has been quiet for days even though it has a 'beta-gamma' magnetic field that harbors energy for M-class solar flares. NOAA forecasters estimate a slim 10% chance that AR1783 will break the quiet with an M-flare on July 21st.
