SAGE-Var is a follow-up to the SAGE and SAGE-SMC Legacy programs. The SAGE-Var program obtained 4 epochs of photometry at 3.6 and 4.5 microns covering the bar of the Large Magellanic Cloud (LMC) and the central region of the Small Magellanic Cloud (SMC) in order to probe the variability of extremely red sources missed by variability surveys conducted at shorter wavelengths, and to provide additional epochs of observation for known variables. The 6 total epochs of observations probe infrared variability on 15 different timescales ranging from 20 days to 5 years.
