P. D'Avanzo (INAF/OABr), D. Malesani (SISSA), G. Tagliaferri, S. Campana 
(INAF/OABr), S. Piranomonte (INAF/OAR), G. Chincarini (Univ. 
Milano-Bicocca), and L. Stella (INAF/OAR), report on behalf of the 
MISTICI collaboration:

After the revision of the coordinates suggested by Butler & Bloom (GCN 
4500) of the X-ray afterglow of GRB 060108 (Oates et al., GCN 4443; 
Page, Oates & Burrows, GCN 4444; Sakamoto et al., GCN 4445), we looked 
again at our VLT near-infrared images (D'Avanzo et al., GCN 4452; 
Piranomonte et al., GCN 4484).

The object reported by Butler & Bloom (GCN 4500) is clearly detected in 
our deep K-band image, taken on Jan 11.28 UT, and is likely extended. 
However, it is not seen in the (shallower) J-band image taken on Jan 
9.31 UT. The implied color is J-Ks > 1.8.
