Fig. 3: Winding flux distributions for AR11318 during the rise phase.
From: Direct evidence that twisted flux tube emergence creates solar active regions
Distributions of (a) \({{{\rm{d}}}}{L}_{{{{{\rm{braid}}}}}}/{{{{\rm{d}}}}}t\) and (b) \({{{\rm{d}}}}{L}_{{{{{\rm{emerge}}}}}}/{{{\rm{d}}}}t\) of AR11318 at \(t=42\,\)h. The orange contours indicate a field strength of 800 G (and thus indicate the sunspot locations). X and Y are distances along the \(x\)- and \(y\)-directions.
