Covered period: 2012 December 17-23
LAT Mission week: 237.57 - 238.57

  • A flare of the BL Lac object PKS 0426-380 was observed in the days between Dec. 17 and 20 (see ATel#4660).
  • Blazars PKS 0454-234PKS 1510-08, 4C +38.41 (also known as B2 1633+38) , PKS 1424-41, and MG1 J123931+0443 (also known as GB6 J1239+0443) were in high state with a daily flux level equal or above 1E-6 in some days of the week.   
  • Bright blazars detected with daily flux between about 0.5E-6 and 1.0E-6 in some days of the week were: CTA 102,  3C 454.3,  RX J1700.1+6830 (also known as GB6 J1700+6830) on Dec. 23,  3C 273, PKS 0521-36B2 1846+32A (2FGL J1848.5+3216, a FSRQ)  or  B2 1846+32B (2FGL J1848.6+3241, an AGN of unknown type) on Dec. 18, and PMN J0948+0022.
  • Other blazars detected during the week, with daily flux value equal or below 0.5e-6 level were: S4 1749+70, Mkn 421, PKS 0250-225, PKS 0537-441, S5 0716+71, PKS 1124-186, BL Lacertae,  PKS 0135-247, TXS 1318+225,  3C 66A  and W Comae (on Dec. 23).

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.
