We report Optical & IR follow up observations of 3C120. The Fermi LAT collaboration announced this target was flaring in ATEL #6529. It was also monitored in optical in ATEL #6542 and in X-ray using Swift in ATEL #6606. The following observations were made using the SMARTS 1.3-m telescope at Cerro Tololo, Chile from 2014-10-07 to 2014-10-21. Typical errors in the optical are +/- 0.03 and typical errors in the near IR are +/- 0.05. Further multi-wavelength observations are encouraged.
