The majority of solar flares exhibit increased soft X-ray emission several minutes before any detectable increase in hard X-ray emission which traditionally delineates the beginning of the impulsive phase. This is referred to as the pre-impulsive phase. In this study we present evidence of high velocity upflows at the footpoint of a coronal loop during the pre-impulsive phase of a X2.0 solar flare. Emission lines of Fe XXIII and Fe XXIV observed by Hinode/EIS exhibited blue shifts at a loop footpoint of up to approximately 150 km/s, while plasma at the loop apex was stationary, and redshifted along the other leg of the loop. The upflows appeared 5 minutes before a detectable increase in hard X-rays. This indicated that energy deposition and heating was occuring at one footpoint only; and that material expanded to fill the coronal loop due to pressure imbalance. A preliminary analysis is outlined for this single event and a search of the EIS flare catalogue is underway to determine if such high temperature up-flows occur in the pre-impulsive phase of other flares.
