Gorosabel (IAA-CSIC)\n\nreport:\n\n\nFollowing the detection of the very high fluence gamma-ray burst GRB\n021008 (GCN 1617, 1625), we have observed the IPN error box given by\nHurley et al. (GCN 1629) with the 2.2m telescope at Calar Alto (Spain)\non Oct 14.21 UT (3 x 200 sec, I band) and Oct 15.21 UT (5 x 200 sec,\nR band) at a high airmass, just before the twilight (5.9 and 6.9 days,\nrespectively, after the burst trigger). The combined R-band image goes\n~1 mag deeper than the corresponding DSS-2 red image. No optical\ntransient is found down to the DSS-2 limit (R ~ 20).\n\nThis message can be cited.",
