Fermi LAT Weekly report N. 357


Covered period: 2015 April 6 - 12
LAT Mission week: 357.57 - 358.57

  • Flare of the optically-selected and polarized BL Lac object SDSS J084411.67+531250.7 (NVSS J084411+531250, BZB J0844+5312, 3FGL J0843.9+5311) on April 6 with daily averaged flux of 0.3e-6, about 50 times the averaged flux reported in the 3FGL catalog. A high-urgency ToO observation by Swift showed a X-ray and optical-UV spectral energy distribution brightening of a factor of about 5 with respect to archival observations. This correlated flaring activity observed by Fermi and Swift confirms the identification of 3FGL J0843.9+5311 (2FGL J0843.9+5312) with SDSS J084411.67+531250.7. More details in ATel#7358.

  • The VHE gamma-ray blazar PKS 1441+25 is detected in high activity state on April 7 and 10 both with daily averaged flux 0.6e-6 and photon spectral index 1.7.
  • PKS 1510-08 detected in high state all week long with daily averaged fluxes between 1.8e-6 and 3.0e-6.
