(GROWTH) collaborations
We report observations of 58 galaxies in 90% localization of the BNS merger
candidate, S190425z, detected by LIGO/Virgo (GCN #24168) using the Lulin
One-meter Telescope (LOT) in Taiwan. The observation started at 2019-04-25
14:11:07 UT, ~5.9 hours after the trigger. All images were taken in R-band
with 180 second exposure time. No significant transient can be identified
brighter than R~20 mag (AB). The galaxy coordinates are listed below.
We thank the staff in Lulin Observatory for helping the observations.
