Covered period: 2010.Jan.18 - 2010.Jan.24
LAT Mission week: 85.57 - 86.57
- 3C 454.3 still dominates extragalactic gamma-ray sky with the flux of (5.7 +/-0.3)*10^-6.
- OX 169 flared on January 18, 2010, peaking at flux (1.4 +/-0.4)*10^-6, reported in ATel #2393.
- PKS 0420-01 showed a gradual increase of gamma-ray flux in the last ~40 days. On January 21, 2010, is showed a flare with a peak flux of (0.8 +/-0.2)*10^-6. On the same day, BL Lacertae showed a short gamma-ray flare with the peak flux of (1.1 +/-0.5)*10^-6 in the six-hour interval centered on 2010 January 21.375 (UT). These events were reported in ATel #2402.
- 3C 66A was detection on weekly timescale with a high significance level and flux of (0.27 +/-0.06)*10^-6. However, no exceptional activity of this source was observed.
- ATel #2403 reported detection of a new unidentified gamma-ray source in the Galactic plane by AGILE satellite. Preliminary analysis revealed no Fermi/LAT sources near the reported position both on daily and weekly timescales...
- Other bright (flux>0.5) extragalactic sources detected on weekly timescale:
PKS 1510-08, CGRaBS J2345-1555, PKS 0402-362, 4C 21.35, 4C 38.41
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.
