Fermi LAT Weekly Report N. 228



Covered period: 2012.October.15 - 2012.October.21
LAT Mission week: 228.57 - 229.57

  • PKS 1424-41 has been significantly detected almost every day in the first three weeks of October. This increase in activity was highlighted with an Astronomer's Telegram ( #4494) on 2012 Oct 17 when its daily averaged flux reached (1.4+/-0.2)X10-6
  • S4 0218+35 remained very bright all week, with a daily averaged flux between (1.4+/-0.3)X10-6 and (2.8+/-0.4)X10-6.
  • 4C +38.41 was bright and detected every day this week with a daily averaged flux between (0.8+/-0.2)X10-6 and (1.4+/-0.2)X10-6.
  • CTA 102 was bright and detected every day (except Oct 20) this week with a daily averaged flux between (1.1+/-0.3)X10-6 and (1.8+/-0.7)X10-6.
  • NRAO 676 was bright and detected every day (except Oct 17) this week with a daily averaged flux between (1.3+/-0.4)X10-6 and (2.4+/-0.4)X10-6.
  • Sporadic daily detections of blazars (fluxes below 1X10-6): PKS 0521-36, S3 0827+24, PKS 2155-304, B3 1343+451, 4C +01.28, PKS 2201+171, NGC 1275.
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.
