EUV images in the AIA 131 Å, 171 Å, and 304 Å wavelengths (from top to bottom), showing the circular-ribbon flare and jet eruption. The white and black contours in panel c1 respectively represent the positive and negative magnetic fields of the HMI LOS magnetogram scaled at ±120 G. In panel c3 the green and blue curves mark the locations of filaments F1 and F2, respectively, as observed in panel c1. (The associated movie is available online).
