A. C. Gilmore and P. M. Kilmartin (Mt John Observatory of the University of
Canterbury) report:
We stacked 20 x 60 second clear exposures with an Apogee U-47 CCD on a 0.6-m
f/13.5 reflector at Mt John Observatory, centred on February 28 09:54 UT (11.5
hours after the burst.) Our images do not show any new object in or near the
Swift-BAT error circle when compared with DSS-2 red and DSS-2 infra-red images.
