VLA images of the SN 2025ulz field at ≈10 GHz. In all panels, we show a black circle centered on the HST position of SN 2025ulz with radius equal to the nominal FWHM of the VLA synthesized beam (0﹩\mathop{.}\limits^{{\unicode{x02033}}}﹩6 in the top and middle panels; 0﹩\mathop{.}\limits^{{\unicode{x02033}}}﹩2 in the bottom panel). The actual VLA beams are plotted with black ellipses in the bottom-left corner of each panel. The optical position of the host-galaxy SDSS J155154.16+305409.3 is marked with a black cross. Maps’ colors span the ±5 ×  RMS flux density range. The radio counterpart of SN 2025ulz is detected at the ≈6σ level in the central panel. The counterpart is not detected in preceding observations (top panel) and fades below detection level in the later observations (bottom panel).
