Kasliwal (Caltech)\nreport on behalf of the GROWTH collaboration\n\nWe obtained a spectrum of the optical afterglow (GCN #25555, #25558,\n#25560) of GRB190829A (GCN #25551, #25552) with the Low Resolution\nImaging Spectrometer (LRIS; Oke et al. 1995) on the Keck I telescope.\nObservations began at UT 2019-08-31 03:35 for a total exposure time of\n20 minutes. The afterglow is clearly detected in the data, and\nexhibits a featureless red continuum. Narrow galaxy emission lines of\nH alpha and [S II]  are detected at a redshift of z = 0.078,\nconsistent with the redshift of the underlying galaxy. The red\ncontinuum and host emission features are consistent with those\nreported in GCN #25563 and #25565.",
