Abstract:
We report 330 supernova candidates discovered by the 2.5-m Wide Field Survey Telescope (WFST) during the first two months of its deep high-cadence ugr-bands survey.

We report 330 reliable supernova candidates discovered by the Wide Field Survey Telescope (WFST; Wang, T., et al., 2023, SCPMA, 6609512) deep high-cadence ugr-bands survey ("DHugr," a typical 5-sigma limiting magnitude of ~ 23 mag in g band; Jiang, J.-a., et al. in prep) from Dec 14, 2024*. After crosschecking with the existing TNS reports, 316 supernova candidates are newly reported and other previously reported supernovae/candidates have been discovered by WFST DHugr earlier (Meng et al., AstroNote 2025-57). A list of the 330 supernova candidates can be found here.

We note that real-time WFST transient alerts will be issued from March 2025. 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 35 reliable supernova candidates have been discovered in our reference images, exact detection dates and brightness of the transients need to be further investigated.
