GCN Circular 24303
The start time in the previous circular is incorrect and has been corrected here. LIGO/Virgo S190425z: Lulin observations of the Swift/UVOT transient Albert Kong (NTHU), Han-Jie Tan (NCU), Po-Chieh Yu (NCU), Chow-Choong Ngeow (NCU), Wing-Huen Ip (NCU) On behalf of Global Relay of Observatories Watching Transients Happen (GROWTH) collaborations We used the 1m telescope at the Lulin Observatory in Taiwan to obtain g- and r-band images of the transient found by Swift/UVOT (GCN 24296). The observations started at 2019-04-27 19:30 UT and the exposure time is 300s for both filters. With a limiting magnitude of about 21.5 (AB) by comparing to PS1 images, we do not detect the UVOT transient.
