Covered period: 2010.Nov.29 - 2010.Dec.5
LAT Mission week: 130.57 - 131.57
- PKS 0447-439 was detected in high activity state on Dec. 5, with a daily flux of (0.6+/-0.2)e-6.
VHE emission from this source was discovered by H.E.S.S. on November-December 2009 (ATel #2350). PKS 0447-439 has been associated with a BL Lac object at z ~ 0.2 (Perlman et al. 1998, ApJ 115, 1253) or with a Seyfert 1 galaxy located at a redshift of z=0.107 (Craig & Fruscione 1997, AJ, 114, 4).
- 3C 454.3 very bright for all the week, but with a decreasing daily flux from 24.0E-6 to 15.0E-6.
- PKS 0537-441 detected for all the week, with daily flux between 0.4E-6 and 0.9E-6.
- 4C +21.35 detected on four consecutive days this week (Dec. 1-4), with increasing flux between 0.7E-6 and 2.8E-6.
- PKS 2155-304 detected on Dec. 2, 4, and 5, with daily flux between 0.2E-6 and 0.4E-6.
- PKS 2326-502 detected in high activity state on Dec. 3 and 4, with daily flux of 1.0e-6 and 1.3e-6, respectively.
- Sporadic daily detections of blazars: PKS 0524-485 (Nov. 29), B2 1520+31 (Nov. 29), PKS 0402-362 (Nov. 30), B3 1708+433 (Nov. 30, Dec. 1), 3C 66A (Dec. 2), PKS 0336-01 (Dec. 3), CRATES J2237-3921 (Dec. 3).
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.
