TITLE: GCN CIRCULAR NUMBER: 7878 SUBJECT: GRB 080613B - NOT optical and IR nondetections DATE: 08/06/14 01:17:22 GMT FROM: Christina Thoene at Niels Bohr Institute,DARK Cosmo Ctr Christina C. Thoene, Daniele Malesani, Johan P. U. Fynbo (DARK), Lison Malo (Universite de Montreal), Richardo J. Cardenes and Anlaug Amanda Djupvik (NOT) report: We observed the field of GRB 080613B (Markwardt et al., GCN 7873) on June 13 with the NOT on La Palma 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 within the XRT error circle (Mao et al. GCN 7875). The limiting magnitudes are about R=22 mag and Ks=17.6 based on USNO and 2MASS stars in the field respectively.
