Active Region 11476 is decaying further as it gets closer to the limb, with associated spots displaying only rudimentary penumbra. The chance of flares has fallen significantly with NOAA forecasting only a 15% chance of M class flares, and less than 1% chance of X class flares. Only 2 weeks ago this active region presented itself as one of the largest we have seen in years, however it was the spot that never was, and despite it's large size never really released any sizeable flare activity.
