MMFs and the related AFSs in multiwavelength observations at 06:05 UT on 3 April 2013. Panel a): continuum-intensity image showing the positions of the MMFs (M1, M2, M3, and M4) relative to the sunspot. Panel b): MMFs in the magnetogram image. Panels c)−f): the related filaments (F1, F2, F3) in the observations of Hα (panel c)), EUV 304 (panel d)), 211 (panel e)), and 131 (panel f)) Å. The fibrils in F1 showed some twisting (see dotted curves in the black boxes). The blue and green contours denote the continuum intensity and magnetic flux density with the values of [0.3, 0.8] I₁ and [–110] G, respectively. An animation of the HMI continuum intensity, HMI magnetograms, Hα, 304 Å, 211 Å, and 131 Å channels shown in this figure is available in the online edition.
