An image obtained by the LASCO C3 coronagraph on board SOHO at 00:54 UTC on 2026 April 7, approximately 12 minutes before the solar-eclipse image analyzed in this study was captured. The FoV of the LASCO C3 image is 15﹩\mathop{.}\limits^{\unicode{x000b0}}﹩7, comparable to the apparent lunar diameter (16﹩\mathop{.}\limits^{\unicode{x000b0}}﹩9) as shown in Figure 6. The central occulter blocks the direct solar disk, with the white circle indicating the position of the Sun. The bright radial structures extending outward from the Sun are coronal streamers.
