GCN Circular 25595
K. De (Caltech), V. Karambelkar (Caltech), M. M. Kasliwal (Caltech) report on behalf of the GROWTH collaboration We obtained a spectrum of the optical afterglow (GCN #25555, #25558, #25560) of GRB190829A (GCN #25551, #25552) with the Low Resolution Imaging Spectrometer (LRIS; Oke et al. 1995) on the Keck I telescope. Observations began at UT 2019-08-31 03:35 for a total exposure time of 20 minutes. The afterglow is clearly detected in the data, and exhibits a featureless red continuum. Narrow galaxy emission lines of H alpha and [S II] are detected at a redshift of z = 0.078, consistent with the redshift of the underlying galaxy. The red continuum and host emission features are consistent with those reported in GCN #25563 and #25565.
