Covered period: 2012 June 4-10
LAT Mission week: 209.57 - 210.57
- Gamma-ray flaring activity of the BL Lac object PKS 2233–148 (z>0.65). The averaged daily flux level detected on June the 5th was (1.5±0.2)E-6 (see ATEL#4152). PKS 2233–148 was active and bright all the days of the week (daily flux level always above about 0.7E-6).
- The gravitationally lensed blazar PKS 1830-211 showed renewed gamma-ray flaring activity with a daily flux level above 1E-6 in every
day of the week. On June the 6th, in particular, the source reached a daily averaged flux level of (2.2±0.2)E-6 (see ATel#4158).
- Gamma-ray flare of BL Lacertae, peaking on June the 5th (averaged
daily flux level of (2.1±0.3)E-6). The source was detected in high state
most days of the week.
- The Narrow line Seyfert 1 object PMN J0948+0022 showed a flare on June the 9th (daily averaged flux around 1E-6).
- Blazars PMN J2345–1555, PKS 0454–234, CTA 102, 4C +38.41 (S4 1633+38), B3 1343+451, S5 0716+71, Ton 599, PKS 1903-80 were detected in some days of the week in bright state (above about the flux level of 0.5E-6).
- Sporadic daily detections of blazars, with a flux level below about 0.5E-6): B3 1343+451, PMN J2345–1555, PKS 2255–282, OG 50, PKS 1424-41, Mkn 421, Mkn 501, B3 1708+433.
Fluxes are in the unit of photons/cm^2/s above 100 MeV. All uncertainties are statistical only.
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.
