We report an optical spectrum (range 350-870nm) of AT2020ekk, discovered by Koichi Itagaki, that was obtained on UT Mar. 12.85 2020 with the 2.4-m telescope (+YFOSC) at LiJiang Observatory of Yunnan Observatories. This spectrum is quite blue and nearly featureless. A broad emission around 464 nm might be contributed by the NV 461 nm and He II 468.6 nm. A series of narrow and weak H Balmer lines are seen also. These features consistent with a young type II supernova at the flash spectroscopic phase.
