AGILE monitoring of the enhanced gamma-ray emission from the Crab Nebula region

AGILE is monitoring the gamma-ray emission from the Crab Nebula region, and enhanced flux above 100 MeV is currently detected from a source positionally consistent with the Crab Nebula. AGILE-GRID detected the following gamma-ray fluxes above 100 MeV (pulsar plus nebula) MJD=55660.9-55662.9, 2011-04-09 23 45 UT - 2011-04-11 23 45 UT, F = (3.5 1.3) 10^{-6} ph/cm2/sec MJD=55662.9-55664.9, 2011-04-11 23 45 UT - 2011-04-13 23 45 UT, F = (6.5 1.5) 10^{-6} ph/cm2/sec.
