We observed the field of EP260623a (Wang et al. GCN 45020) with the NOEMA interferometer, located at Plateau de Bure (France). We performed multiple visits between the 29th of June and the 25th of August using the 3 and 2 mm bands (this last one only for the first epoch). The afterglow (Li et al. GCN 45021) was detected at around 0.5 mJy on the first visit and was seen to decay until the last epoch, where we still obtain a 4-sigma detection.

We acknowledge excellent support from the IRAM staff. Based on observations carried out under project number S26DT with the IRAM NOEMA Interferometer. IRAM is supported by INSU/CNRS (France), MPG (Germany) and IGN (Spain).
