We observed the afterglow of GRB 240529A (Eyles-Ferris et al. GCN 36556, ) with the NOEMA interferometer, located at Plateau de Bure (France). The observation was performed on the 3rd June 2024 at around 11:00 UT, 5.3 days after the burst onset at the 3 mm band.
The afterglow is detected at a flux density of ~2 mJy, indicating that the peak emission is still at higher frequencies than the 15 GHz detection by AMI-LA (Rhodes et al. GCN 36636).

Based on observations carried out under project number W23DI with the IRAM NOEMA Interferometer. IRAM is supported by INSU/CNRS (France), MPG (Germany) and IGN (Spain).
