GRB 101112A: BOOTES-2/TELMA optical afterglow candidate

Cunniffe, S. Guziy, J. Gorosabel (IAA-CSIC Granada), R. Fernandez-Muñoz
(EELM-CSIC), S. Castillo-Carrion, C. Perez del Pulgar (Univ. of Malaga),
L. Sabau-Graziati (INTA) and A. J. Castro-Tirado (IAA-CSIC) report:
"Following the detection of GRB 101112A by INTEGRAL (Gotz et al. GCNC
11396), the 0.6m TELMA robotic telescope at the BOOTES-2 station in
Malaga (Southern Spain) responded 31 s after reception of the GCN alert
(i.e. 109 s after the onset of the event). Within the IBIS/INTEGRAL
error box, we find a source not present at the DSS-2 red at coordinates
(J2000) R.A.:19:28:54.88, Dec: +39:21:11.6 (error ± 0".5). We measure
R about 18 for the co-added 31 first images (3-s each, using an r' band
filter, at mid exposure time 22:12 UT, i.e. 156-s after the onset of the
burst). The source has gone in the images taken at later times so we
propose this to be the optical afterglow to GRB 101112A. Further
observations are in progress. Multiwavelength observations (including
optical spectroscopy) are requested."
