We observed the Type II supernova SN 2024abbv (ATLAS24qei, TNS Astronomical Transient Report No. 232489) with the Australia Telescope Compact Array (ATCA) at 5.5 and 9.0 GHz on 15 Jan 2025 9:14-13:10 UT. The source was detected at 5.5 GHz with a flux density of 0.15 +/- 0.04 mJy and at 9.0 GHz with a flux density of 0.11 +/- 0.03 mJy. The SN has a redshift of z=0.005277 (TNS Classification Report No. 18703), corresponding to a distance of ~23 Mpc. This implies a luminosity of 9.5E+25 erg/s/Hz at 5.5 GHz and 7.0E+25 at 9.0 GHz, ~63 days after discovery. We would like to extend our thanks to the ATCA staff for enabling these observations. The ATCA is part of the Australia Telescope National Facility which is funded by the Commonwealth of Australia for operation as a National Facility managed by CSIRO. We acknowledge the Gomeroi people as the traditional owners of the Observatory site.
