Solar Activity
Solar activity was very low for most of the week, although in the past 2 days, two large active regions have emerged. NOAA 11190 is the reminants of former 11172 but is currently undergoing significant flux emergence at its center and is classified as a beta gamma region. NOAA 11191 is on the east limb and consists of a large bipolar sunspot with well formed penumbra and is bright in soft X-rays. Both of these regions are producing C class flares and 11191 is likely to continue to do so for at least the next few days.
