Abstract (from CDS):

In the early days of 2010 April, the blazar 3C454.3 (z = 0.859) underwent a strong γ-ray outburst, reaching fluxes (E > 100MeV) in excess of 10–5photon/cm2/s. The Fermi Gamma-ray Space Telescope performed a 200ks long pointed observation starting from 2010 April 5 19:38utc. This allowed us to try probing the variability of the γ-ray emission on time-scales of hours or less. We found the variability on a few hours time-scale. On subhour time-scale we found no evidence of significant variability, although the present statistics is not yet conclusive and further observations are needed.
