  "body": "D. A. Kann, F. Cusano and F. Ludwig (TLS Tautenburg) report:\n\nWe observed the field of the INTEGRAL/Fermi GRB 090817 (Beckmann et al., \nGCN 9815, Wilson-Hodge, GCN 9823) with the 1.34m Tautenburg Schmidt \ntelescope under good conditions. We obtained 3 x 600 sec Rc images at a \nmid-time of 8.015 days after the GRB.\n\nAt the position of the X-ray afterglow (Evans, Guidorzi & Baumgartner, \nGCN 9819, GCN 9825), the USNO-B1.0 object 1341-0096763 is clearly \ndetected. Using the comparison star of Rumyantsev, Pozanenko & Andreev \n(GCN 9828), we find Rc = 19.54 +/- 0.03 mag. This is in agreement \nwith the reports of non-variability (Rumyantsev, Pozanenko & Andreev, \nGCN 9828, Halpern & Ruan, GCN 9837) of this proposed host galaxy/SN \ncandidate (Holland, Breeveld & Baumgartner, GCN 9831, GCN 9834), and a \nstellar PSF is in full agreement with it being a foreground star (Halpern \n& Ruan, GCN 9837, Cenko et al., GCN 9841).\n\nNo further observations are planned.\n\nThis message may be cited.",
