Tagliaferri (INAF-OABr) report on behalf of the MISTICI collaboration:
Following the detection by Swift/XRT (Beardmore et al., GCN 6610) of GRB
070707 (Beckmann et al., GCN 6605; Gotz et al., GCN 6607), we have
inspected our VLT R-band images (D'Avanzo et al., GCN 6609).
Inside the XRT error box, we find a single source with R ~ 23.0
(calibrated using archival instrumental zeropoints), at the coordinates
(J2000, 0.5" error):
RA(2000) = 17:50:58.55
Dec(2000) = -68:55:27.2
At the present stage, we cannot yet assess the relationship of this
source with GRB 070707. Further observations are planned.
