Fermi LAT Weekly Report N. 302


Covered period: 2014.Mar.17 - 2014.Mar.23
LAT Mission week: 302.57 - 303.57

  • 3C 454.3 was detected March 22 and 23 with a daily averaged flux between (1.3 +/- 0.5) and (1.8 +/- 0.7).
  • PKS 1424-418 was detected all week with a daily averaged flux between (0.7 +/- 0.3) and (1.6 +/- 0.4).
  • Sporadic daily detections of blazars (fluxes below 1):PKS 1510-08, 4C +21.35 (PG 1222+216), 3C 279, PKS 0454-234, B2 1520+31, S5 1044+71, PKS 1730-13, NGC 1275 (Per A), 4C +38.41 (S4 1633+38, B2 1633+38).

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.

  • On 2014 March 10 the Crab Nebula has been observed in flaring state showing a daily flux of 5.7+/-0.5 (ATel #5971). Consequently, Fermi interrupted the planned observation to maximize the exposure toward the Crab Nebula.
  • 3C 279 brightened the last day of the week with a daily flux around 1.2.
  • PKS 1424-41observed in the second part of the week with daily average flux of 0.7.

  • B2 1520+31 detected almost all week with an average daily flux of 0.5.
  • NGC 1275 (Per A) observed three times this week (daily flux between 0.4 and 0.5).
  • Mrk 421 detected on March 10, March 11 and March 15 with daily average flux of 0.3.
  • Other blazars detected sporadically (fluxes < 1):4C +21.35(PG 1222+216), 4C +01.02 (PKS 0106+01, OC 12), B2 1144+40, PKS 1510–08, PKS 2326–502, 3C 454.3, 3C 66A, PKS 0454–234, PKS 2155-304, PKS 0301-243

Fluxes are in the unit of 10-6 photons/cm2/s above 100 MeV. All errors are statistical only
