Abstract

We analyze pre-explosion ultraviolet (UV) imaging of the nearby Type II supernova SN 2023ixf in search of precursor variability. No outbursts are seen in observations obtained 15-20 yr prior to explosion to a limit of LNUV1000 LsunL_{NUV} \approx 1000~L_{sun} and LNUV2000 LsunL_{NUV} \approx 2000~L_{sun}. The time period of these non-detections roughly corresponds to changes in the circumstellar density inferred from early spectra and photometry.
