report:
We imaged the field of GRB 170405A detected by SWIFT
(trigger 745797) with the TAROT robotic telescope (D=18cm)
located at the Reunion observatory, France.
The observations started 3.84h after the GRB trigger.
We detected the OT (Troja et al., GCN 20984;
Hui & Meegan, GCN 20986; Vianello & Kocevski, GCN 20987;
Malesani, GCNC 20988):
t0+3.84h to t0+3.97h : R=19.0 +/- 0.2
Magnitudes were estimated with the nearby NOMAD1 stars
and are not corrected for galactic dust extinction.
