Abstract:
We report 1,602 supernova candidates discovered by the 2.5-m Wide Field Survey Telescope (WFST) during the first six months of its wide field survey.

We report 1,602 reliable supernova candidates discovered by the Wide Field Survey Telescope (WFST; Wang, T., et al., 2023, SCPMA, 6609512) wide field survey (WF) from Sep 22, 2025*. After crosschecking with the existing TNS reports, 829 supernova candidates are newly reported and 430 previously reported supernovae/candidates have been discovered by WFST WF earlier. A list of the 829 new supernova candidates can be found here**.

We note that real-time WFST transient alerts for both deep high-cadence ugr-band (DHugr) and WF surveys will be issued from March 2026. Spectroscopic classifications and follow-up observations of future WFST transients 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).

Note*: Additional 100 reliable supernova candidates have been discovered during the period of making reference images, exact detection dates and brightness of the transients need to be further investigated.
Note**: Including 108 previously reported transients from WFST ToO observations.
