Fermi LAT weekly report N. 125

Covered period: 2010.Oct.25 - 2010.Oct.31

LAT Mission week: 125.57 - 126.57

  • The flat-spectrum radio quasar 3C 454.3 is still the brightest extragalactic source on the sky. The largest daily flux this week was (7.6 ± 0.8)e-6 on Oct 28.

  • The flat-spectrum radio quasar 4C +21.35 was bright from Oct 25-29, reaching (1.9 ± 0.4)e-6 on Oct 26.

  • The flat-spectrum radio quasar PKS 2326-502 was detected throughout the week, reaching (1.3 ± 0.3)e-6 on Oct 27.

  • The flat-spectrum radio quasar PMN J2345-1555 was detected throughout the week, reaching (0.7 ± 0.2)e-6 on Oct 29. This is part of ongoing activity reported in several ATels (#2972, #2977, #2986, #2989, #3004).

  • The flat-spectrum radio quasar B2 1846+32A reached (1.1 ± 0.3)e-6 on Oct 29.

  • The BL Lac PKS 0537-441 was detected on Oct 26 at (0.9 ± 0.3)e-6 and again on Oct 31 with a similar flux.

  • The classic BL Lac Mkn 421 was detected on Oct 26 and 31 at (0.2 ± 0.1)e-6.

  • The following sources were detected sporadically (in one of the seven one-day time bins): PKS 2155-304, B3 1708+433, PKS 1730-13. PKS 1730-13 turned out to be the beginning of a flare that was sustained into the following week, as reported in ATel #3002.

  • 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.
