Fermi LAT weekly report N. 206

Covered period: 2012 May 14-20
LAT Mission week: 206.57 - 207.57

  • PKS 1830-211 and PMN J1038-5311 are both in high state being detected most days of the week, showing also a daily flux level above 10^-6 photons cm^-2 s^-1 at least in a couple of days. The daily peak flux observed is about 1.9X10^-6 on May 18 for PKS 1830-211, and about 1.5X10^-6  on May 15 and 18 for PMN J1038-5311.
  • Other blazars detected in high state in one day of the week are PKS 1510-089 reaching the daily flux level of 10^-6 on May 14,  OJ 248 (S3 0827+24) flaring at about 10^-6 on May 17, and OJ 287 flaring at about  10^-6 on May 18.
  • CTA 102, S5 0716+71, PKS 2326-502PMN J2345-1555, and PKS 0454-234 are detected most days of the week.
  • Sporadic detections of blazars with daily flux level below 10^-6: BL Lac, PMN J2250-2806, 4C +21.35  PKS 2255-282, PKS 2233-148, PG 1218+304.
  • Sporadic detections of blazars with daily flux level below 0.5x10^-6:  B2 1520+31, PKS 0341-256, 3C 66A, PKS 2233-148,  SBS 0846+513 (a narrow line Sy1 galaxy), Mkn 421,  PKS 2123-463,  TXS 1616+517, PKS 2155-304, PKS 0341-256, GB6 J0850+4855, B3 1343+451.

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.
