Fermi LAT weekly report N. 98



Covered period: 2010.Apr.19 - 2010.Apr.25

LAT Mission week: 98.57 - 99.57





  • PKS 0426-380 detected on 5 days this week with a daily flux above 0.5 +/- 0.2 X 10-6 (peak on Apr 22, with a daily flux (0.9 +/- 0.3) X 10-6).

  • PKS 0537-441 detected all week long with daily flux approaching and around (1 +/- 0.2) X 10-6.

  • S5 0716+714 detected on Apr. 19 and 22 with daily fluxes around (0.5 +/- 0.2) X 10-6.

  • CGRaBS J0850-1213 was detected on Apr. 19, 24, and 25 with daily fluxes not exceeding (0.8 +/- 0.2) X 10-6.

  • 4C +21.35 has been detected all week long in a high state with daily fluxes above (1.5 +/- 0.2) X 10-6. A peak in intensity has been observed on Apr. 24, when the daily flux was (8.1 +/- 0.7) X 10-6 (see ATel#2584).

  • PKS 1424-41 has reached daily fluxes around (1.0 +/- 0.2) X 10-6 on Apr. 21 and 22 (see ATel#2583).

  • PKS 2233-148 was detected on Apr. 19 and 23 with daily fluxes around (0.7 +/- 0.3) X 10-6.

  • 3C 454.3 still bright through the week but with daily flux fading from (9.5 +/- 0.8) X 10-6 to (3.4 +/- 0.5) X 10-6.

  • PKS 0906+01, HB89 1738+499, PKS 0301-243, PKS 0805-07, MRk 421, CGRaBS J1033+6051, and CGRaBS J1739+4955 were detected in one day of the week (flux below 1 X 10-6 ).



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.
