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 and . The time period of these non-detections roughly corresponds to changes in the circumstellar density inferred from early spectra and photometry.
