"On Apr 9, 2005 the REM telescope observed the field of GRB050408
(Sakamoto et al. GCN 3189) from La Silla Observatory (Chile).
The field was imaged with both REM instruments REM-IR and ROSS in
V, R, I, J, H and Ks filters starting at 00:31 UT (approximately 8.2
hours after the burst) for a total integration time of 200 seconds
for each filter.
No sources are detected within SWIFT XRT error circle (Wells et al. GCN
3191) and at the position of the Optical Transient (Ugarte et al., GCN
3192; Huang et al., GCN 3196) down to a limiting magnitude of 18.5,
18.3, 17.9, 16.8, 17.4, 18.4 (5-sigma upper limit)
