Hartmann (Clemson University), Brian Murphy\n(Butler University), and Kenneth Rumstay (Valdosta State University)\nreport:\n\nWe observed the field of GRB 090915 (Cummings & Markwardt GCN 9912,\nFermi-GBM trigger 274721737) using the 0.9m SARA telescope located at Kitt\nPeak National Observatory beginning 44173 seconds after the burst and\ncontinuing for about half an hour.  Observations were carried out under\ngood weather conditions at high airmass.\n\nIn 21 minutes of stacked exposures, we marginally detect a source within\nthe XRT error circle (Beardmore, Page, & Sakamoto, GCN 9914) at R ~ 20.5\n+/- 0.3 (as compared to field stars using the USNO B1.0 catalog).  The\nobject is not found in the DSS catalog.  Variability can not be\nestablished from these single-epoch observations.  It is likely that the\nabove source is the same identified by Hoversten & Sakamoto (GCN 9918). \nTo establish the decay, follow-up observations are encouraged.\n\nThis message may be cited.",
