Title:  Short-term Activity in Young Solar Analogs

Knowing the chromospheric activity in YSAs gives us an insight into the conditions in the early solar system when life was establishing a foothold on the earth. To complement a 7-year history of monitoring YSAs on long and medium timescales, a program of high-cadence, high signal-to-noise spectroscopy started in 2013 at VATT, a 1.8-m telescope situated on Mt. Graham, AZ, to detect activity behavior on timescales of minutes to hours. This is addressing the question of the energy output and frequency of flares on a subset of our program stars. Initial, spectacular results will be presented.
