In this paper we present and discuss observations of an energetic mass flow event associated with a chromospheric flare observed on AT Mic. The spectroscopic observations were made in May 1992 using the SAAO 1.9m telescope. The useful wavelength range covered was 3750 to 4150 Angstroms incorporating the higher Balmer lines and Ca II H & K lines.
