Fermi LAT weekly report N. 267

LAT Mission week: 267.57 - 268.57

  • Blazar 4C +38.41 (B2 1633+38) is still in high state, detected all week with a daily averaged flux between (0.9 ± 0.2) and (2.0 ± 0.3).
  • PKS 1424-41 was detected all week except on July 19 and 21, with daily averaged flux between (1.1 ± 0.3) and (1.8 ± 0.4).
  • PKS 0426–380 was detected all week: from July 15 to July 17 with daily averaged flux of (0.5 ± 0.2); and then brightening from July 18 to July 21, with daily averaged flux between (0.8 ± 0.2) and (1.2 ± 0.2).
  • 3C 454.3 was detected on July 15, July 20 and July 21, with daily averaged flux between(0.9 ± 0.3) and (1.0 ± 0.3).
  • 3C 279 was detected on July 15 with daily averaged flux of (1.0 ± 0.2).
  • Sporadic daily detections of blazars during the week, with daily flux value equal or below 0.6 are: PKS 0454–234, PMN J2345-1555, Mkn 421, PKS 0440–00, PKS 0521-36, NGC 1275, B2 1520+31, CGRaBS J0211+1051, PKS 0805–07, 4C +01.02, OJ 287.

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.
