Fermi LAT Weekly report N. 399

Covered period: 2016 January 25-31
LAT Mission week: 399.57-400.57

  • Flare of the FSRQ PKS 0514-459 (RX J0515.7-4556, z=0.194), detected for the first time with daily flux level 0.8e-6 on Jan. 25 (see ATel#8595 for more details). It was also detected on Jan. 26. The source is located 0.18 degrees from the radio blazar candidate PMN J0514-4554 and at 0.73 degrees from the radiogalaxy Pictor A.
  • Outburst activity of CTA 102 has continued all week with daily flux level between 2.3e-6 and 4.0e-6, peaking on Jan. 25 and 29.
  • 3C 454.3 with daily fluxes between 2.7e-6 and 3.9e-6.
  • PKS 1502+106 in flaring activity with daily fluxes between 0.9e-6 and 1.3e-6, peaking on Ja. 28 and 30.
  • The gravitationally lensed blazar PKS 1830-211 in flaring activity with daily fluxes between 0.9e-6 and 1.3e-6, peaking on Jan. 28 and 30.
  • 3C 279 detected in the second half of the week with daily fluxes around 0.9e-6.
  • PKS 1424-41 with daily fluxes between 0.6e-6 and 0.8e-6.
  • AO 0235+164 with daily fluxes between 0.5e-6 and 0.7e-6.
  • BL Lac with daily fluxes between 0.3e-6 and 0.7e-6. A hard state of the source was observed on Jan. 28 with spactral photon index (E>100MeV) of 1.6 and a few photons above 10 GeV.
  • S5 0836+71 (4C +71.07) with daily fluxes between 0.4e-6 and 0.7e-6.
  • PKS 0106+01 (4C +01.02) and PKS 2023-07 both detected in high state on Jan. 30 with daily flux level 0.7e-6.
  • ON 393 (B2 1255+32, z=0.805949) is a FSRQ detected for one of the first times in a daily interval on Jan 28. Values are daily flux 0.3e-6 and hard photon index 1.7.
  • Flare of TXS 0358+210 (GB6 J0401+2110, z=0.834) detected at 0.5e-6 on Jan. 30.
  • Increased activity of the TeV blazar 1ES 1215+303 detected on Jan. 30 with daily flux level 0.2e-6 and photon index 1.6. Alternatively another TeV blazar 1ES 1218+304 could be associated with this detection.
  • Other blazars of the week detected, also sporadically, around or below about 0.5e-6: Mkn 421, Mkn 501, PKS 0454-234, B2 0110+31 (4C +31.03), PMN J2345-1555, PKS 2155-304, S4 1749+70, NGC 1275 (Per A, 3C 84), PKS 1313-333, PKS 0208-512, 1ES 1959+650, B2 1144+40, B2 1520+31, PKS 1717+177, B2 1633+38 (4C +38.41), S4 1030+61, B2 1846+32B.

Fluxes are in the unit of photons/cm^2/s above 100 MeV. All uncertainties are statistical only.
Note. All the flux reported above are by 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.
