Discovery of the Closest Ultra-stripped Supernova: SN 2021agco in UGC 3855

We present the discovery and studies of the helium-rich, fast-evolving supernova (SN) 2021agco at a distance of ∼40 Mpc. Its early-time flux is found to rise from half peak to the peak of −16.06 ± 0.42 mag in the r band within ${2.4}_{-1.0}^{+1.5}$ days, and the post-peak light curves also decline a...
