GCN Circular 20065

Subject
GRB 161015A: Swift/UVOT observations

M. De Pasquale (MSSL-UCL) and J. Cannizzo (NASA/UMBC) report on
behalf of the Swift/UVOT team:

The Swift/UVOT report started to observe the field of the putative X-ray
afterglow of GRB 161015A, the Fermi/LAT burst (Ohno et al. GCN
Circ. 20054, D'Avanzo et al. GCN Circ. 20057), 38 ks after the
LAT trigger.

No optical counterpart to this source is found. The 3 sigma upper limit
is given in the table below.

  T_start (s)  T_end (s)  Exposure Time (s)  filter   3s UL

   37991        45608         1210             u      >20.35

The magnitudes in the table are not corrected for the Galactic extinction
due to the reddening of E(B-V) = 0.04 in the direction of the burst
(Schlegel et al. 1998).
