We report the detection of radio emission from the nearby supernova, SN2020qmp (discovered by the Palomar Gattini-IR survey; TNS report 78883; TNS classification 7259; TNS AstroNote 2020-149).

We observed SN2020qmp with the Jansky Very Large Array (VLA) on 2020 September 13. The observation was conducted at 6 GHz (C-band) in the B configuration. We performed an analysis of the data using the 3C286 as a flux calibrator and J1146+3958 as a gain calibrator.

A single point source is detected in the C-band image at RA=12:08:44.45 Dec=+36:48:17.29 (consistent with the position of SN2020qmp) at a flux level of ~0.25 mJy. This corresponds to a luminosity of 4.3e25 erg/s/Hz.

We encourage further high cadence multi frequency radio observations with the VLA and other facilities.
We thank the VLA and NRAO staff for scheduling and performing this observation.
