report on behalf of a larger collaboration:
"Following the detection by SWIFT of GRB 060427 (V. Mangano
et al. GCNC 5006), we have obtained R & I-band images
at the 2.5m Nordic Optical Telescope (+ ALFOSC), starting
on Apr 27.876 UT (i.e. 9.25 hr after the onset of the event).
At the position of the X-ray afterglow detected by SWIFT/XRT
(V. Mangano et al. GCNC 5010), no optical source is detected
in the 600s R-band image, down to a limiting magnitude of
R = 23.5."
