A. Corsi and D.R. Bhakta (Texas Tech. U.) report on behalf of a larger collaboration:

We imaged again the position of GRB 141109A (D'Avanzo et al., GCN 17037) with 
the Karl G. Jansky Very Large Array (VLA) from 2.4 d to 8.3 d after the BAT trigger. 
For the radio counterpart consistent with the location of the GRB NIR, optical, and 
X-ray afterglows (Covino et al., GCN 17039; Xu et al., GCN 17040; Osborne et al. 
GCN 17043; Corsi, GCN 17070), we estimate the following preliminary fluxes: 

Mean Epoch (d) | Freq. (GHz) | Flux (uJy) | map rms (uJy)
-------------------------
 2.4 | 21.8 | 51 | 9
-------------------------
 6.3 | 14.0 | 50 | 6
-------------------------
 8.3 |  6.2 | 57 | 6
