D. A. Perley (Caltech), A. Horesh (Weizmann Institute), D. A. Frail (NRAO) report:
We imaged again the the position of GRB 141121A (Lien et al., GCN 17075) with
the Karl G. Jansky Very Large Array (VLA), at a mean epoch of about 16.3 days
after the burst. At this time, we detect the radio afterglow of GRB 141121A
(Anderson et al., GCN 17099; van der Horst, GCN 17104; Corsi, GCN 17124),
and estimate a preliminary flux of about 228 uJy at 6.2 GHz and 186 uJy at 14 GHz.
The map rms is about 9 uJy at 6.2 GHz and 7 uJy at 14 GHz.
Further observations are planned.
