Cenko (NASA-GSFC), D.A.Perley (Caltech), report \non behalf of a larger collaboration:\n\n\"On September 30.18 UT (1.75 days after the burst) we observed the field \nof the Fermi/LAT GRB 140928A (Desiante et al. GCN 16847, Varela et al. \nGCN 16849) with the Gemini-South telescope equipped with the GMOS \nspectrograph. We obtain 2x1200s exposure under non optimal conditions \n(1.5-2 arcseconds seeing) with the R400 grating, covering the 6000-10000 \nAngstrom wavelength range.\n\nWe detect a featureless continuum down to 6000A, no features are \ndetected neither in emission nor in absorption.\n\nWe thank Cristiano Guidorzi for providing a finding chart and the Gemini \nstaff for carry out this observations.\""
