Skynet observed the field of IGR J17062-6143 using the PROMPT telescopes
located at CTIO in Chile following Swift trigger 525148 (Barthelmy et al.)
and beginning 16.9 minutes after the trigger. Earlier observations were
delayed due to evening twilight. We detect a fading optical afterglow
at RA=17:06:16.3, Dec=-61:42:40.3 with the following preliminary magnitudes:

Magnitudes were calibrated to five stars in the USNO-B1.0 catalog.

Further BVRI observations are planned.
