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.
