Fermi LAT weekly report N.182

Covered period: 2011.Nov.28 - 2011.Dec.04

LAT Mission week: 182.57 - 183.57

  • B3 1343+451 was detected every day. It flared up to a daily flux of (1.2 ± 0.2) x 10-6 (on Nov 29th) before declining to (0.4 ± 0.2) x 10-6. This was the highest gamma-ray flux level detected from this very high redshift (z=2.534) FSRQ and was reported in ATel #3793. This source has been intermittently detected since early October and had a steadily rising daily-averaged flux from the preceding week.

  • PKS0454-234 was detected every day except Nov 29th with daily-averaged fluxes between (0.4 ± 0.2) x 10-6 and (1.7 ± 0.2) x 10-6.

  • B2 1520+31 detected on Nov 28th, Nov 30th, Dec 1st through 3rd with daily flux declining from (1.2 ± 0.2) x 10-6 to (0.4 ± 0.2) x 10-6.

  • 4C +28.07 was detected every day starting from Nov 28th reaching a peak daily-averaged flux of (1.0 ± 0.2) x 10-6 on Dec 3rd.

  • PKS1244-255, PKS 0537-441, 4C71.07, Mrk 421, J2345-1555, BL Lac, PKS1424-41, PKS2320-005, TXS0059+581, NGC 1275 (3C84), OJ287 detected in one or two days of the week (flux below 1 x 10-6 ).

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.
