  • PKS 1510-08 was detected on Apr. 24 with daily averaged flux of (1.2 +/- 0.3).
  • On Apr. 27 The LAT detected a strong high-energy GRB with a flux of (10 +/- 1.0) (see GCN Circular #14471 and GCN Circular #14508).
  • Sporadic daily detections of blazars (fluxes below 1): Mkn 421, CTA 102, OX 169, B2 2319+31, S5 1044+71.

Fluxes are in the unit of 10-6 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.

Fermi LAT Weekly Report N. 253



Covered period: 2013.April.08 - 2013.April.14
LAT Mission week: 253.57 - 254.57

  • Mrk 421 detected from April 9 to 14, with a daily flux between (0.4±0.1) X 10-6 and (0.8±0.2) X 10-6. See ATel#4977.

The modified Fermi survey mode provides an increase in the exposure on Mrk 421 by about a factor of 2.
