Period:  January 19th to March 17th in 2009

  The Fermi/LAT team is organizing a multi-wavelength campaign on the blazar (FSRQ) 3C279 (z=0.536) starting at the end of January and finishing at the middle of March, including various satellites (IR to gamma-ray). We encourage any multi-wavelength observations from radio to TeV to obtain the broad band SED throughout the period.
