report on behalf of the Watcher collaboration:

The Watcher 40cm robotic telescope, located at Boyden Observatory,
South Africa, began imaging the field of INTEGRAL GRB 070615
(Mereghetti et al., GCN 6537) at 02:22:08 UT, 1m22s after the IBAS
trigger.

Initial observations were performed at high airmass and show no new
source down to an R-band limiting magnitude of approximately 15 (in
comparison with USNO-B1). Observations and analysis are ongoing.
