Fermi LAT Weekly Report N. 324


Covered period: 2014.Aug.18 - 2014.Aug.24
LAT Mission week: 324.57 - 325.57

  • On Aug. 18 and 19 the Crab Nebula was observed in flaring state showing an average daily flux of (7.5±0.6) and (5.4±0.7), respectively (ATel #6401).
  • 3C 454.3 was detected all week long with daily averaged fluxes between (5.2 ± 1.4) and (2.1 ± 0.6).
  • PKS 0502+049 was detected in flaring state on Aug. 22 and 23, reaching average daily fluxes of (0.9 ± 0.2) and (0.7 ± 0.2), respectively. It corresponds to approx. 20-30 times the flux reported for this source in the 2FGL catalog.
  • Sporadic daily detections of blazars (daily averaged fluxes below 1 unit): PKS 1510–08, B2 1520+31, S5 0716+71, AO 0235+164, 4C +55.17 (OK 591, S4 0954+55).

Fluxes are in the unit of 10-6 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.
