Abstract:
We report the radio detection of SN2023ixf in the nearby galaxy M101 at 10 GHz

We report results from our radio campaign of SN2023ixf from NSF’s 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.
