MASTER-SAAO  robotic telescope (MASTER-Net: 
located in SAAO was pointed to the  GRB160804A  (Swift trigger= 707231 
came only from (Marshall et al., GCN19761)
  at 2016-08-04 17:59:48 UT (16h27m01s after the trigger time). We have set 
of  images with unfiltered 
m_lim=20.7 (540s exposure).

We see the Swift/UVOT source (Breeveld et al., GCN 19764) at Ra Dec 
(2000)=14:46:31.14 +09:59:56.7  with unfiltered m_OT~ 20.3.

There is  a Sloan galaxy  in 0.182" with green g=21.7, red r=21.2m, i.e. 
possible host galaxy for this GRB.
