SDO/AIA 171 Å images showing the evolution of two EUV jets. The color scale is the same as in Fig. 1. The labels jet 1 and jet 2 denote the two jets close to each other both in time and space. Grey/black lines in panels c) and g) represent positive/negative polarities of the line-of-sight magnetic field at 03:56:51 UT. The contour levels of B_LOS are −1200, −900, −600, 50, 300, and 600 G.
