C. Guidorzi (U. Ferrara), S. Kobayashi (LJMU), C.G. Mundell (U. Bath),
A. Gomboc (U. Nova Gorica), I.A. Steele (LJMU) on behalf of a large
collaboration report:
We began observing Swift trigger 783893 (D'Avanzo et al. GCN 22067) on
October 29, 06:48:16 UT (20 minutes since the trigger time) with one of
the 1-m LCO McDonald telescopes in the SDSS-I filter. Within the
Swift-BAT error circle a comparison with the SDSS field reveals no
uncatalogued source down to i'~20 mag (SDSS calibrated) at a mid time of
26 minutes post trigger (5x120 s exposure).
