SMART Hα line-center ((a)–(c)) and +0.5 Å ((e)–(f)) and AIA 193 Å ((g)–(j)) images show the ejection of the small jet at the southern boundary of the coronal hole. Panel (d) is an HMI LOS magnetogram showing the magnetic field configuration. The boundary of the coronal hole is overlaid on the magnetogram and 193 Å images as a dotted curve, while the white arrow indicates the propagation direction of the EUV wave. The FOV for each frame is 220'' × 220''.
