Covered period: 2009.May.18 - 2009.May.24
- Fermi LAT detection of recent activity in a source positionally consistent with the candidate blazar 4C31.03 (see ATel #2054).
- PKS 1510-089 and PKS 1502+106 are the brightest blazars with fluxes (>100 MeV) always above 1e-6 ph/cm^2/s and exceeding 2e-6 ph/cm^2/s on one day of this week.
- 3C 454.3 reached a flux (>100MeV) greater than 3e-6 ph/cm^2/s but only one day. The rest of the week it has been around 1e-6 ph/cm^2/s.
- S5 0716+714 showed up with a daily flux (>100MeV) of 0.7e-6 ph/cm^2/s.
- PKS 0440-00 continues its activity with the highest weekly flux since Fermi launch and one daily flux (>100MeV) of 1.9e-6 ph/cm^2/s.
- 3C 279 brightens up after a low state period, with fluxes (>100MeV) above 1e-6 ph/cm^2/s.
- LSI +61 303 bright and detected in some days of this week.
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.
