Fermi LAT weekly report N. 106

Covered period: 2010.Jun.14 - 2010.Jun.20

LAT Mission week: 106.57 - 107.57

  • PKS 0521-36 was detected for the first time in a daily time scale with
    a flux above the threshold of (1.0 ± 0.2) X 10-6 in June 17, an Atel was
    issued about the flaring activity of this source (see ATel #2683).
    A Swift ToO was obtained (see ATel #2689).

  • 4C +21.35 (June 18, see ATel #2687): Fermi/LAT has observed an increasing
    gamma-ray flux from a source positionally consistent with 4C +21.35 (also known as PKS 1222+21 and PKS B1222+216) at z=0.43. On June 18,
    2010 this blazar showed a bright flare with a daily flux (E>100MeV) of (12.46 ± 0.79) X 10-6. A peak flux (E>100MeV)
    of (16.42 ± 1.89) X 10-6 was reached between 12:00 and 17:01 UT.

    The same flare has been detected also by the AGILE (see ATel #2686) and MAGIC (see ATel #2684) telescopes, a SWIFT follow up has been obtained (see ATel #2698).

  • 3C 454.3 was detected all the week.

  • CGRaBS J1033+6051 was detected above the threshold in the daily time scale on June 15.

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.
