WFST0532hscl (AT 2025dug) was detected by the Wide Field Survey Telescope (WFST; Wang, T., et al., 2023, SCPMA, 6609512) deep high-cadence ugr-bands survey ("DHugr," Jiang, J.-a., et al. in prep) from Dec 14, 2024. WFST0532hscl was first detected on MJD 60736.789 at g = 22.1 ± 0.1 mag. The transient is offset by 2.1" from a galaxy (redshift z = 0.1150 from SDSS).
Subsequent WFST observations revealed rapid evolution: The brightness of WFST0532hscl was increased by 1.9 mag (~-0.5 mag/day) in g-band and g-r color of ~-0.1 mag on Mar 6 (MJD: 60740.813).
Given the fast evolution of the transient, follow-up observations are encouraged.
This report is based on observations obtained with the 2.5-m Wide Field Survey Telescope (WFST) at Mt. Saishiteng, Lenghu, China. The WFST science products have been made possible through the contributions of the University of Science and Technology of China (USTC) and the Purple Mountain Observatory (PMO).
