Covered period: 2014.Mar.31 - 2014.Apr.6
LAT Mission week:304.57 - 305.57
- The outburst of the FSRQ 3C 279 continued during the week and reached the highest daily averaged of (7.0±0.7)E-6 on April 5. This is the highest gamma-ray flux ever observed by the LAT from 3C 279. Strong variability on six-hour timescales has been detected, showing a minimum flux of about 1.8E-6 and maximum of about 10.4E-6 on April 5.
- 3C 454.3 was in a high state during the week reaching a peak daily flux of about 2.4E-6 on April 5.
- PKS B1424–418 was detected during the week with a maximum daily flux of about 1.4E-6 on April 2.
- A non-2FGL gamma-ray source was detected on April 3 with a daily flux of about 0.4E-6 at RA=37.4583 Dec=-48.0284 with a 1-sigma error circle radius of 0.22. A possible counterpart is the FSRQ PMN J0231-4746 (z=0.77) located 0.35 degrees away.
- A non-2FGL gamma-ray source associated with PKS 2136-642 (ATel#5695) was detected on April 4 with a daily flux of about 0.5E-6.
- The FSRQ PKS B1319–093 was detected on April 1 with a daily flux of (0.50±0.13)E-6. The flux level corresponds to 27 times the flux reported on the 2FGL catalog.
- Sporadic daily detections of blazars (fluxes below 1): Mkn 421, PKS B1056–113, PKS 1510–08, S4 1144+40, OP 313 and 4C +21.35.

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.
