Title:  YSOVAR: Young Stellar Variability on 6-7 Year Timescales

YSOVAR (Young Stellar Object VARiability) is the name given to a group of Spitzer Space Telescope programs (PI: J. Stauffer) all aimed at time-series monitoring of young stars. We have extensive mid-infrared (3.6, 4.5 um) time-series photometry of a dozen star-forming regions on a variety of timescales ranging from minutes to years. This poster will summarize our results for variability on the longest timescales to which we are sensitive, 6-7 years.
