Caption: Figure 1.

Left: original L-band detection of CC 1 in L. M. Close et al. (2025a). Middle: new H-band detection of WISPIT 2 c following RDI. We show a confined annulus that was used for optimal stellar signal subtraction. Note that the bright arch on the right side of the annulus is the forward scattering side of the circumstellar disk. Right: detection map of the WISPIT 2 c planet with VLTI/GRAVITY on the night of 2025 October 4. The map shows the periodogram power maps of a point source companion as a function of angular offset from the star, where the companion location corresponds to the strongest peak.
