Fermi LAT weekly report N. 222



Covered period: 2012.September.03 - 2012.September.09
LAT Mission week: 222.57 - 223.57

  • The gravitationally lensed blazar S3 0218+35 re-brightened on September 3, with a daily flux of (1.0±0.2) X 10-6, reaching its maximum on September 6, with a daily flux of (2.4±0.3) X 10-6. This flaring activity possibly represents the gravitational lens time delayed counterpart of the previous flaring event that started on August 25. See ATel#4361. The source continued to be detected on September 7, and 9 with a daily flux of (1.0±0.2) X 10-6 and (1.2±0.3) X 10-6, respectively. See ATel#4371.
  • Mkn 421 detected on September 3, 4, 5, 7, 8, and 9, with a daily flux between (0.2±0.1) X 10-6 and (0.5±0.2) X 10-6.
  • B3 1343+451 detected on September 3, 4, 5, 6, 7, and 9, with a daily flux between (0.4±0.1) X 10-6 and (0.9±0.2) X 10-6.
  • 4C 38.41 detected on September 3, 5, 7, and 8, with a daily flux between (0.5±0.2) X 10-6 and (0.9±0.2) X 10-6.
  • S5 0716+714 detected on September 6, 7, 8, and 9, with a daily flux between (0.4±0.1) X 10-6 and (1.1±0.2) X 10-6.
  • PKS 1124-186 detected on September 3, and 4, with a daily flux of (0.5±0.2) X 10-6.
  • PKS 2233-148 detected on September 6, and 9, with a daily flux of (0.5±0.2) X 10-6 and (0.4±0.1) X 10-6, respectively.
  • Sporadic daily detections of blazars (fluxes below 1 X 10-6 ): PKS 0250-225 (September 3), 1H 1013+498 (September 3), S4 0954+65 (September 4), PKS 2326-502 (September 7), PKS 1424-418 (September 9).
  • 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.
