Scientific paper

The Submillimeter Array (SMA) performs ongoing flux density monitoring of quasars that are typically bright in the mm/submm bands, in order to optimally choose quasars for use as interferometric calibration sources. Through this monitoring effort, we discovered and reported in ATEL #2150 that that the quasar 3C454.3 (J2253+161) was flaring strongly at millimeter wavelengths starting in mid-2009. Flaring activity has also been reported in the IR, optical, and gamma ray bands (see ATEL #2155, ATEL #2182, ATEL #2200, ATEL #2201).
