Fig. 4: Winding flux distributions of AR11318 during the plateau 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 \(t=78\) h. The orange contours indicate a field strength of \({B}_{z}=800\) G. X and Y are distances along the \(x\)- and \(y\)-directions.
