Abstract (from CDS):

We analyze pre-explosion ultraviolet 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 LNUV ≈ 1000 L⊙ and LFUV ≈ 2000 L⊙. The time period of these non-detections roughly corresponds to changes in the circumstellar density inferred from early spectra and photometry.
