Period:  January 19th to March 17th in 2009

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