We report results from our radio campaign of SN2023ixf from the Karl G. Jansky Very Large Array (VLA). We acquired a second epoch with the VLA on June 17th 2023 beginning on-source at 00:53:26 UT (~29 days since discovery, Project Code SF151070, PI: Margutti) at X-band (8-12 GHz) with the array in BnA-configuration for a duration of approximately 40 minutes on-source. We find evidence for statistically significant radio emission at the location of SN2023ixf with a preliminary flux density of 41 +/- 8 uJy. Previously, our first epoch of observations led to a non-detection (Fnu < 33 uJy at 10 GHz on May 23rd 2023, 4 days since discovery, AstroNote #2023-146).
Further observations are planned.
We thank the entire VLA team for carrying out these observations.
