Covered period: 2011 October 03 - 09

LAT Mission week: 174.57 - 175.57




  • 4C +28.07 detected in a flaring state, reaching a daily peak flux of
    (2.3 ± 0.3) x 10-6 on Oct. 4 (Atel #3670, #3676).

  • OJ 287 was detected throughout the week with increasing flux,
    reaching a daily value of (0.8 ± 0.2) x 10-6 on Oct 7 (ATel #3680).

  • 3C 446 showed a fast flare on Oct. 8, with a daily average value of
    (1.5 ± 0.4) x 10-6 (ATel #3675).

  • PKS 0454-234 was detected multiple times during the week, with daily
    flux levels around 1 x10-6.

  • TeV source PKS 1510-089 started to brighten on Oct. 7, reaching a
    daily flux value of (3.3 ± 0.5) x 10-6 by the end of the week.

  • TeV source NGC 1275 showed a fast outburst on Oct. 6, with a daily
    flux of (0.6 ± 0.2) x -6.

  • Other active extragalactic sources were: S5 0716+71, PKS
    0627-199
    , 4C +38.41.

  • The last six hours on Oct. 5 were impacted by pointed observations
    toward the Earth (nadir).



Fluxes are in the unit of photons/cm2/s above 100 MeV. All errors are statistical only.



Note. All the fluxes reported above are from the ASP analysis and should be considered preliminary and should not be used for publication, however they are indicative of the flux range and the current status of a source. Source association is done on the basis of source location, considering spatial coincidence only, and it is not indicative of an identification.
