  • NGC 1275  (Per A) increased its activity during the week reaching a daily flux level of about 1E-6 on January 2, 3 and 5. 
  • S5 1044+71 rather bright during the week and peaking on December 31, January 1 and 2 at about 0.8E-6.  
  • Other blazars detected in some days of the week with a daily flux lower than about 0.7E-6: PG 1553+113, PKS 1510-089, Mkn 421, PKS 0735+17, PKS 0208-512, B3 1343+451, PKS 0426-380, PKS 0454-234, 3C 454.3, PKS 0336-01,  4C +28.07 (OD 258, B2 0234+28).
  • Three GRBs clearly detected by the LAT during the week: GRB 131231A, GRB 140102A and GRB 140104B.

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.
