The AGILE satellite, currently in its Science Verification Phase, during the Observing Block that started on 2007-11-02 12:00 UT, detected significant gamma-ray emission from a source coincident with the blazar 3C 454.3, as reported in ATEL #1278. The source continues to be active in > 100 MeV gamma rays, showing variability on day-to-day time scales, with particular activity within the last two days. We strongly encourage continued multi-frequency observations of the field of the gamma-ray source detected by AGILE.
