Covered period: 2014.June.9 – 2014.June.15
LAT Mission week: 314.57 - 315.57
  • The FSRQ 3C 454.3 was detected in high state all week long (daily flux above 3 × 10–6). The peak of the gamma-ray emission was reached on Jun. 15 when the observed source flux was (1.4 ± 1)× 10–5. Further details are reported in ATel #6236.
  • PKS 1424–418 was detected with flux equal to 0.8 × 10–6 on Jun. 13 and 15.
  • PKS 1510–08 was detected with flux above 1 x 10–6  on June 12, 13 and 15.
  • Sporadic activity (daily fluxes below 1.0 × 10–6) observed from S5 0716+71, PKS 0426–380, PKS 0454–234, NGC 1275, PKS 1346-112, S5 0836+71, 4C +71.07, 3C 279, S5 1044+71, B2 1144+40, PKS 1824-58, PKS 0727-11, 4C +50.11.
Fluxes are in the unit of photons cm–2s–1 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.
