"The REM telescope, currently in commissioning phase, observed the whole
error box of the INTEGRAL GRB 040106 (Mereghetti et al., GCN #2505)
starting at 04:45 UT of 7 January 2004 (i.e. about 11 hours after the GRB
trigger) in V, R and I filters with the ROSS spectrograph/imager.
The total exposure time was 180 s for each filter.
Observations in the infrared bands with the REMIR camera were not
possible at this stage due to technical reasons.
When comparing the images with the DSS2, no new source was found within
the INTEGRAL error box down to the following limiting magnitudes:
V ~ 19.3
R ~ 18.7
I ~ 18.2
Moreover, no source was detected inside the XMM-Newton error circle
(Ehle et al., GCN #2508).
