Extended Data Fig. 3: EUV signatures of nanojets N1, N2 and N3.

a–c, Time–distance maps in all AIA and IRIS channels (SOT stopped observing at this time) along cuts corresponding to the axis of nanojets N1 (a), N2 (b) and N3 (c) shown, respectively, in Figs. 2, 3 and 4. The temporal and spatial extent shown is the same as that of the time–distance diagrams shown in those figures. The N1 and N2 cuts trace part of the first clustered appearance of nanojets and the ejection of plasmoids. All cuts show an intensity enhancement that is similar across most EUV channels, indicating very fast and substantial heating.
