Display (overlayed on the pertinent average images) of the pixels that were associated with transient bightenings in ALMA 1.26 mm (red), AIA 1600 Å (green), and AIA 304 Å (blue) for scan 1 data. In the images of the top row, we mark all events at each wavelength. In panels d and e of the bottom row we mark only the paired events, that is, those that were detected both at 1.26 mm and 1600 Å, respectively. Panel f: average 1.26 mm image. The white circles denote the ALMA field of view.
