GRB 160303A SMA observation

Y. Urata (NCU), K.Y Huang (NTNU), and G. Petitpas (SMA)

We observed the optical afterglow position of GRB 130303A (Butler et
al., GCN Circ. 19131) using the Sub-Millimeter Array (SMA). The
observation in 230 GHz band was started at March 3 12:47 (UT) about
1.9 hrs after the burst.  Our preliminary analysis shows no
counterpart brighter than 2.4 mJy (3-sigma).
