Poonam Chandra (NCRA-TIFR) reports:

We carried out Giant Metrewave Radio Telescope (GMRT) observations of
GRB 130427A at 1390 GHz band on 2013 June 07.38 UT. We don't detect the
GRB in our radio observations. The 3-sigma upper limit at the GRB afterglow
position (Levan et al., GCN 14742; de Ugarte Postigo et al., GCN 14743;
Foley et al., GCN 14745; Cucchiara et al., GCN 14748) is 273 uJy.

We thank GMRT staff for making these observations possible.
