SDO/AIA 211 Å running difference image showing the coronal dimming associated with the CME observed on 2024 August 5 at ≈13:28 UT from AR13767 (Section 2 of the main text). The white circle indicates the solar limb. Solar north is straight up and east is to the left. The red line indicates the location of slit 4 of VELC on the west limb. The center of the slit is at r = 1.17R_⊙. The numbers 225°–315° on the white circle correspond to the solar position angles.
