Oksanen (Nyrola Observatory, Jyvaskyla, Finland) reports to the AAVSO\nInternational High Energy Network the following optical observations of\nGRB071010B (GCN #6871, Markwardt et al.):\n\nArto Oksanen reports the detection of an optical transient located at\nRA 10:02:9.26, Dec +45:43:50.3 (J2000) at an initial unfiltered magnitude of\n\n17.538 calibrated relative to USNOB R-band magnitudes.  Midpoint of the\nexposures is 2007 Oct 10, 21:11:05 UTC, approximately 25 minutes after the\ntrigger.\n\nThere are no comparably bright stars within 0.5 arcminutes, and no minor\nplanets in the area.\n\nSubsequent unfiltered images place the star fainter than 18th magnitude\n(unfiltered) indicating the object has faded since observations began.\nAnalysis of additional unfiltered, Rc, Ic, and V images will be forthcoming.\n\n\nThe AAVSO thanks the Curry Foundation for their continued support of the\nAAVSO International High Energy Network.",
