TITLE: GCN GRB OBSERVATION REPORT NUMBER: 3587 SUBJECT: GRB 050712, optical observations DATE: 05/07/13 09:07:18 GMT FROM: Sylvio Klose at TLS Tautenburg A. Zeh, S. Klose, F. Ludwig, B. Stecklum, Thueringer Landessternwarte Tautenburg, report: We observed the field of GRB 050712 (Grupe et al., GCN 3573) in VRI with the Tautenburg Schmidt telescope starting 21:15 UT on July 12. The stacked R-band images show a faint source at the position reported by Rol et al. (GCN 3575). We estimate R>~20 and note, however, that this source might also be present on the DSS2 red plates. No source is visible in I, implying I>~19.
