We obtained 30 s i-band images of the following GLADE galaxies (Dalya
et al. 2018, MNRAS, 479, 2374) in the LIGO/Virgo localization region of
S190425z (GCN 24168) with the MMTCam instrument on the MMT 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 ~21 mag within
the 2.7 arcmin field of view.
