Christina C. Thoene, Daniele Malesani, Johan P. U. Fynbo (DARK),
Anlaug Amanda Djupvik, Richardo J. Cardenes (NOT) and Lison Malo
(Universite de Montreal) report:

We observed the field of GRB 080613B on June 13 with the NOT using StanCam
and NOTCAM. Observations of 4x300s in R band were obtained with StanCam
starting at UT 21:57 and 5x270s with NOTCAM in the Ks band starting UT
23:17.
In the stacked images of both filters we do not detect any optical
counterpart. The limiting magnitudes are about R=22 mag and Ks=17.6
based on USNO and 2MASS stars in the field respectively.
