Covered period: 2012.Jul.02-2012.Jul.08
LAT Mission week: 213.57-214.57
- On July 3 the Crab nebula region reached a daily average flux level of (5.5±0.7) X 10-6 which is twice its average level. This triggered TOO observations lasting 300 ks (elapsed time) and was reported in ATel#4239. After staying at elevated daily levels and showing considerable variations on shorter time scales, the daily flux dropped back to an average level on July 7.
- NRAO 676 was very bright all week and reached a record daily average flux level of (4.5±0.4) X 10-6 on July 4th. The discovery of this source was communicated to the community last month (ATel#4182) when its daily average flux reached (2.3±0.3) X 10-6 on 2012 June 16.
- S5 0716+714 was detected on all except one day from July 3 through July 8 with daily average flux in the range (0.6-0.9) X 10-6.
- PKS 2326-502 was detected on July 2, July 3 and again on July 8 with daily average flux in the range (0.6-1.1) X 10-6.
- Sporadic activity (fluxes below 1e-6): BL Lacertae, PKS 1510-08, PKS 2255-282, 4C +28.07, Mrk 421, PKS 0906+01, NGC 1275, 4C +55.17, MG2 J043337+2905, OG 050, TXS 0141+268, S4 0218+35, PKS 0804-05, 4C +38.41.
Fluxes are in the unit of 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.
