tokens: features may be seen within a “mossy” region that is oriented roughly along the axis of the supergranular network elements. In this case, the presence of small loops is hardly surprising, given that the underlying network is interspersed with minority-polarity flux elements. Figure 12. Moss-like region associated with supergranular magnetic network located just north of NOAA 12321, 2015 April 18. The circled area has radius 30′′ and is centered at (265′′, 391′′). Top panel: sharpened 17.1 nm image recorded at 14:29:47 UTC. Second panel: sharpened 19.3 nm image recorded at 14:29:42 UTC. Third panel: sharpened 21.1 nm image taken at 14:29:47 UTC. Bottom panel: HMI magnetogram recorded at 14:29:49 UTC and saturated at ±100 G. In this case, the looplike fine structure seen inside the moss is consistent with the presence of positive-polarity flux elements scattered in and around the negative-polarity network. Finally, Figure 13 shows an inverted-Y structure embedded in an area of moss inside NOAA 12335, as observed at 06:14 UTC on 2015 May 5. The base of the structure is rooted in strong negative-polarity plage, but the bright moss occupies a much wider area, extending through the weaker-field region to the south. The dark areas in the 17.1 nm image in the top panel represent fibrilar and filament material located near large- and small-scale polarity inversion lines. Figure 13. Moss region inside NOAA 12335, 2015 May 5. The circled area has radius 12′′ and is centered at (−376′′, −152′′). Top panel: 17.1 nm image taken at 06:14:35 UTC. Second panel: sharpened version of the same image. Third panel: sharpened 19.3 nm image taken at 06:14:30 UTC. Bottom panel: HMI magnetogram recorded at 06:14:51 and saturated at ±100 G. The inverted-Y structure is located in strong negative-polarity plage, but the underlying moss extends southward into areas of weaker photospheric field. These examples suggest that a strong underlying photospheric field is neither a necessary nor a sufficient condition for the presence of bright moss. 5. Summary and Discussion We have presented illustrative examples of inverted-Y structures embedded inside Fe ix 17.1 nm moss, where the underlying photospheric field was purely unipolar according to simultaneous HMI magnetograms. (Additional examples may be seen in Figures 2, 4, and 5 of Wang 2016 .) The triangular or dome-shaped bases of these structures had horizontal dimensions of ∼3′′–6′′ or ∼2–4 Mm. In the standard topological interpretation, the base contains minority-polarity flux, with a null point located at its apex. The lifetimes of the looplike footpoint features ranged from less than a minute to the order of an hour, with the smaller features generally being shorter-lived than the larger ones. As an alternative possibility that does not require the presence of minority-polarity flux, the triangular structures might represent canopies overlying individual granular cells, with thermal pressure dominating above the
