A. Corsi (Texas Tech U.) reports on behalf of a larger collaboration:
We observed the location of GRB 141026A (Hagen et al., GCN 16950) with the
Karl G. Jansky Very Large Array (VLA) in its C configuration. Observations were
carried out in the frequency bands 18.7-24.9 GHz and 4.5-7.8 GHz. A provisional
reduction shows marginal detections at 21.8 GHz (at about 1.1 d and 4.3 d after the
burst), and a clearer detection at 6.2 GHz (at about 6 d after the burst), of a source
consistent with the location of the GRB optical afterglow (Littlejohns et al. GCN 16952;
Varela et al., GCN 16953; Gorosabel et al., GCN 16954; Perley et al. GCN 16955).
We estimate preliminary fluxes for this source of:
Mean epoch | Freq. (GHz) | Flux (uJy) | map rms (uJy)
------------------------------
6.5 hr | 21.8 | 11 | 11
------------------------------
1.1 d | 21.8 | 43 | 11
------------------------------
4.3 d | 21.8 | 31 | 8
------------------------------
6.0 d | 6.2 | 91 | 7
