Abstract
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 L NUV ≈ 1000 L ⊙ and L FUV ≈ 2000 L ⊙. The time period of these non-detections roughly corresponds to changes in the circumstellar density inferred from early spectra and photometry.
