Fine-scale activity and the outflowing fluctuations. (a) AIA 193 Å imaging, with black dashed lines marking the sampling path at multiple altitudes. (b)–(h) Sampling of AIA 193 Å imaging at corresponding altitudes, showing fine-scale activities such as plasma blobs, fluctuations, and jets within the reconnection event. Black arrows indicate the movement directions of plasma blobs and jets. Blue crosses represent wave troughs, and red crosses wave peaks.
