Following GCN 44239 we re-observed the field of EP260321a (Huang et al., GCN 44068) with the Karl G. Jansky Very Large Array (VLA) in its A-configuration. Our observations were conducted at about 22 days post trigger at a nominal central frequency of 6 GHz. We report no significant variation of the radio source at a position compatible with that of SN 2026gzf (Corcoran et al., GCN 44105, Rastinejad et al., GCN 44107).
