TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1826 SUBJECT: GRB 030115, simultaneous observations by BOOTES-1 DATE: 03/01/17 13:57:22 GMT FROM: Alberto Castro-Tirado at Inst.de Astro. de Andalucia A. J. Castro-Tirado (IAA-CSIC Granada and LAEFF-INTA Madrid), T. J. Mateo Sanguino (CEDEA-INTA Huelva), A. de Ugarte Postigo (Oss. Astron. di Brera), M. Jélinek, P. Kubánek, R. Hudec (ASU-CAS Ondrejov), S. Vitek, P. Páta (FEL-CVUT Praha) and J. Á. Berná (Univ. de Alicante) on behalf of the BOOTES team, report: "We have obtained several unfiltred exposures (45-s each) under good metereological conditions covering the GRB 030115 HETE-2 error box (Kawai et al. GCN 1816). The images covered the period 03:22:35 - 03:24:52 UT 15 Jan 2003 (i.e. between 1 and 138-s after the trigger) with the very wide- field camera of BOOTES-1 (http://www.laeff.esa.es/BOOTES). After a visual inspection of the HETE-2 error box in the frames, we do not find evidence of optical emission, in particular simultaneously to the burst itself, for which we have an image covering the time interval 03:22:35- 03:23:20 UT. Therefore we derive an upper limit of R = 10 for any optical emission simultaneous to this 20-s long GRB." This message can be cited.
