Fermi LAT weekly report N. 193

Covered period: 2012.February.13 - 2012.February.19

LAT Mission week: 193.57 - 194.57

  • PKS 1510-08 was detected everyday with daily flux reaching a peak of (4.9±0.5) X 10-6 on Feb. 17. By Feb. 18, the daily flux had declined to the level of (3.0±0.4) X 10-6.

  • PKS 0454-234 was detected four times during the week and reached a daily flux peak of (1.1±0.2) X 10-6 on Feb 15 and maintained a daily flux at slightly below this level for the next two days. A GCN Notice was issued about this source on Feb. 16 as the flux of the source had increased by 5 sigma to this peak value on the timescale of 1 day. No ATel was issued as a GCN Notice had been issued and a previous ATel for this source had been issued in October for a higher flux.

  • PKS 0402-362 was detected almost everyday with daily fluxes ranging from (0.4±0.1) X 10-6 to a peak value of (1.1±0.2) X 10-6 reached on Feb. 18.

  • Sporadic activity (fluxes below 1 X 10-6): B3 1343+451, PKS 2123-463, PKS 2326-502, 4C +55.17, PKS 0716+714, PKS 2255-282, PKS 1424+240, Mkn 421, PKS B1424-418, PKS 0537-441, PMN J0531-4827, PKS 1424-41, BL Lacertae.

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.
