Flare activity in late M stars remains an interesting topic since there is as yet no well tested model of how these convective stars generate the magnetic field that underlie activity such as flares, and the rate and strengths of the flare can impact the evolution of the atmospheres of planets orbiting them We present observations of two flares observed on the M8 star VB10 with the Habitable zone Planet Finder (HPF) on the Hobby Eberly Telescope. HPF is designed to be very stable for precision radial velocities but its NIR coverage (810-1280 nm) and queue scheduled operations allow us to obtain multiple observations to analyze the properties of the flares. A combination of the 10 m telescope aperture with the nondestructive read readout with our H2RG enables us to obtain a time resolution of ~ minutes on this late type M dwarf, which helps us resolve the evolution of the flare. We present our analysis of the Ca II infrared triple lines as well as Pa $\gamma$ and $\delta$ to place constraints on the time behavior and physical conditions of the emitting material.
