  IceCube-160806 (Cowen, GCN 19787)  was in BDRG FOV of 47 deg from the 
axis of the most illuminated BDRG-1 detector (Direction of BDRG-1 axis
RA 05h05m08.96s DEC -25o24'44.54").

No significant GRB was detected by BDRG/Lomonosov in the 
interval +/-50 s from the moment of IC-160806 160806, 12:21:33. Upper 
limits (3 sigma) for 1 s exposition from BDRG-1 background counts:

<0.23 cm-2 s-1 for 20-60 keV,

<0.13  cm-2 s-1 for 60-300 keV

Fermi GBM event 160806 14:01:00.00 source was out of 
BDRG FOV and was shadowed by Earth at 160806 14:01:00.000UT (BDRG-1 axis 
RA 05h14m17.069s.DEC -11o30'33.16", BDRG-2 axis RA 05h30m09.243s.DEC 
-78o50'16.92",BDRG-3 axis RA 11h16m39.621s.DEC -01o02'44.44").
