We observed GRB 260924A (Fermi GBM, GCN 45712; D’Elia et al., GCN 45713) with the Karl G. Jansky Very Large Array (VLA) at multiple frequencies beginning on 2026 Sep 26 at 14:36 UT (2.6 days after the burst).
In preliminary analysis, we detect a radio counterpart at 15 GHz with a flux density of ~0.6 mJy at the position:
RA (J2000) = 08:55:03.106 +/- 0.001”
Dec (J2000) = +12.02.35.24 +/- 0.03”
This is consistent with the X-ray position (Evans et al., GCN 45715) and optical position (Izzo et al., GCN 45718; Klingler et al., GCN 45735). Further observations are planned.
We thank the VLA staff for scheduling and executing these observations.
