A view of all previous radio-observed SNe Ibn and the upper limits on luminosities, including 10 GHz detections and nondetections for SN 2023fyq. The nondetections are shown with downward-facing triangles and are all 3σ limits. SNe 2006jc, 2019qav, 2019aajs, and 2020bgq were observed quite early, and thus their radio evolution could still be consistent with SN 2023fyq, but SN 2015G clearly shows upper limits that are much deeper than the observed radio emission from SN 2023fyq. Future deep observations between 50 and 500 days post-explosion will be key to constraining the subclass.
