"YSOVAR: Young Stellar Object Varability"
 

Variability is a defining characteristic of young stellar systems, and optical and near-infrared variability have long been used to select and characterize the photospheric properties of young stars.  With YSOVAR, a GO6 Spitzer Exploration Science program with over 500 hr of observation we are performing time domain observations over a wider range of wavelengths. These data will help to reveal and study the some of the time-variable phenomena at work during the star formation process. In this talk I will summarize the first results obtained with these observations.
