We present the discovery and analysis of SN\,2022oqm, a Type Ic supernova (SN) detected \(<1\)\,day after explosion. The SN rises to a blue and short-lived (2\,days) initial peak. Early-time spectral observations of SN\,2022oqm show a hot (40,000\,K) continuum with high-ionization C and O absorption features at velocities of 4000\,km\,s\(^{-1}\), w...
