A.J Nayana  (NCRA-TIFR), Poonam Chandra (NCRA-TIFR), A. R. Rao (TIFR), Dipankar
Bhattacharya (IUCAA) and Varun Bhalerao (IUCAA) report:

We carried out Giant Metrewave Radio Telescope (GMRT) observations of GRB 160623A
(Vianello et al. GCN Circ. 19553) at 1460 MHz band on 2016 Aug 04.91 UT. We detect a
4.5-sigma source at the GRB position (Vianello et al. GCN Circ. 19553) with a flux
density of 207+/-78 uJy. This is most likely the radio afterglow of GRB 160623A. Map rms
is 50 uJy.

We thank GMRT staff for making these observations possible.
