Granada), report:
"We have obtained a mosaic of images (3 fields) covering the
entire IPN error box for GRB 031111 (Hurley et al. GCN 2443)
with the 0.8-m IAC80 telescope at Observatorio del Teide starting
on Nov 13.07 UT (31.7-h after the GRB). None of the co-added
images (4 x 600-s exposure time for each field) reveals any new
(or strongly variable source) when comparing with the Digital
Sky Survey (II epoch)".
