Fermi LAT weekly report N.217


Covered period: 2012.Jul.30 - 2012.Aug.05
LAT Mission week: 217.57 - 217.57

  • Four sources were detected every day of the week: S5 0716+71, Mkn 421, PKS 2233-148, and PKS B1424-418. The flux of S5 0716+71 was 0.7 X 10-6, but peaked just above 1.0 X 10-6 on Aug. 2 and 3; Mkn 421 and PKS 2233-148 showed a constant behavior with the daily flux in the range 0.4-0.6 X 10-6 and 0.5-0.8 X 10-6, respectively; PKS B1424-418 was seen more variable with flux flickering between 0.8 and 1.5 X 10-6.
  • PKS 2326-502 was detected in the first 4 days of the week with daily flux in the range 0.6-0.8 X 10-6.
  • Sporadic activity (fluxes below 1.0 X 10-6) observed from 4C +21.35 (0.4 on Jul. 31), 4C +38.41 (0.9 on Aug. 3), PKS 0244-470 (0.7 on Jul. 31 and Aug. 5), PKS 0735+17 (0.2 on Jul. 30), CTA 102 (0.5 on Jul. 30 and 0.8 on Aug. 1), PG 1246+586 (0.2 on Aug. 5), PKS 1424+240 (0.3 on Aug. 3), PKS 2155-304 (0.1 on Aug. 4), and PKS 2255-282 (0.4 on Jul. 31).

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.
