Fermi LAT Weekly report N. 318


Covered period: 2014 July 7 - July 13
LAT Mission week: 318.57 - 319.57

  • Lens B0218+35 (S3 0218+357) detected in flaring state on July 13 at a daily flux of (0.6 ± 0.1). The gamma-ray lensed blazar displayed a peculiar hard spectrum with photon index of 1.3 ± 0.1 (see ATel#6316).  
  • New LAT source, Fermi J1433-1806, detected on July 10 at a daily flux of 0.62 ± 0.06 and a photon index of 2.1 ± 0.1 (see ATel#6310). The closest candidate counterpart is PKS 1430-178 (z=2.331).
  • 3C 454.3 detected all week long with flux between 2 and 5.
  • PKS 1730-130 reached a daily flux of (1.2 ± 0.2) on July 10.
  • 4C +21.35 (PKS 1222+216) observed in three days of the week with daily average flux of 0.6.
  • NGC 1275 (Per A) detected in three days of the week reaching a daily flux of (0.9 ± 0.2) on July 10.
  • Sporadic activity (daily fluxes below 1.0) observed from PKS 1510–08, Mrk 421, PKS 2155-304, PKS 2326–502, PKS 0426-380, S5 0716+714, Mrk 501.

  • 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.
