A day on and the contorted light bridge of AR11445 is still present - the tenuos filaments arcing across one side of the spot to the other. Sadly this is a sign of a decaying sunspot, but regardless makes for a great sight! Taken with the 100mm frac @ 2500mm fl, continuum & fringe killer filters, Lunt wedge DMk31 camera.
