On 2019-04-25 19:21:09 UT we obtained two g-band images of the GW optical
counterpart candidate ZTF19aarzaod (Kasliwal et al. 2019, GCN 24191) with
the Las Cumbres Observatory 1m telescope at the Siding Spring Observatory
in Australia. We detect the candidate with a magnitude of g = 21.3��0.14
(using PSF fitting), consistent with the Tan et al. (2019, GCN 24193)
measurement.
