  • Blazar 4C 21.35 (also known as PKS 1222+21) still bright, detected all week with a daily flux between (1.2+/-0.6)E-6 ph cm-2 s-1 and (2.3+/-0.4)E-6 ph cm-2 s-1, peaking on May 18th.

  • PKS 1424-41 detected most days this week, with increasing daily flux between 0.6 and 1E-6.

  • PKS 0537-441 detected most days this week, with daily flux between 0.6E-6 and 1.1E-6.

  • Blazar PKS 0426-380 detected on four days this week, with daily flux between 0.5 and 1.4E-6.

  • Blazar CGRaBS J1312+4828 detected on three consecutive days this week (May 18th - May 20th) with an average daily flux of about 0.35E-6 ph cm-2 s-1.

  • 3C 454.3 very bright all the week with daily flux above 3.5E-6.

  • Sporadic daily detections of blazars 3C 273, PKS 2155-304, PKS 0332-403, 4C +55.17, PKS 1510-089 and CGRaBS J1700+6830.

Fluxes are in the unit of photons/cm^2/s above 100 MeV.

Note. All the flux reported above are by 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. - Please acknowledge the LAT team if you use information from this report.
