Margutti (Northwestern U), and M. Nicholl (U Edinburgh) report:

We continued observations first reported in GCN 25366. We obtained 60s i-band images
of the following galaxies from the GLADE catalog (Dalya et al. 2018, MNRAS, 479, 2374)
in the LIGO/Virgo localization region of S190814bv (GCN 25324) with the IMACS imager 
on the Magellan Baade 6.5-m telescope:

Comparison of the images to the PS1 3pi survey (Chambers et al. 2016,
arXiv:1612.05560) reveals no new sources brighter than ~22.0 mag within
a 7.6 arcmin field of view.

We especially thank Tyler Gardner for taking these observations at Magellan.
