- NGC 1275 was detected on Oct. 20 and 24 (daily flux below 0.7 X 10-6).
- PKS 0426-380 was detected on Oct. 18, 21, and 23 (daily flux below 0.7 X 10-6).
- PKS 0524-485 was detected on Oct. 18, 20, and 21 (daily flux between 0.3 and 0.9 X 10-6).
- B2 0619+33 continued to be detected through the entire week (flux between 0.8 and 1.4 X 10-6).
- Mkn 421 was detected on Oct. 18, 23, and 24 (daily flux at 0.3 X 10-6).
- 4C 21.35 was relatively bright during all week, with daily flux below 1.6 X 10-6.
- PKS 1830-21 continued to be detected with a peak flux of 4.6 X 10-6 on Oct. 18.
- The FSRQ PKS 1846+32A (CGRaBS J1848+3219) appeared on Oct. 17 with a flux of 0.7 X 10-6, when a simultaneous near-infrared flare was observed (ATel#2953). The source increased the gamma-ray flux up to 2.2 X 10-6 on Oct. 18 (see ATel#2954). In the following days the flux level stabilized between 0.7 and 1.2 X 10-6.
- The FSRQ PMN J1913-3630 appeared on Oct 21 and 22. In the first day the daily flux was 1.3 X 10-6 and an ATel was posted (ATel#2966). The source was not detected previously neither by LAT or by EGRET.
- PKS 2155-304 continued to be detected through the week (flux between 0.5 and 0.9 X 10-6).
- 3C 454.3 was very bright during all week, with daily flux above 3.9 and up to 5.1 X 10-6.
- PKS 2326-502 was detected on Oct. 20, 22, and 24 (flux between 0.7 and 1.0 X 10-6).
- The FSRQ CGRaBS J2345-1555 appeared in the last day of the week with a flux of 0.6 X 10-6. The source showed an increased activity in the optical and a joint ATel with the ATOM team was posted (ATel#2972).
- Sporadic activity observed from PKS 0537-441 (Oct. 19 and 21), CGRaBS J1033+6051 (Oct. 19 and 20), B2 1348+30B (Oct. 23), and B3 1708+433 (Oct. 18). All fluxes below 1.0 X 10-6.
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.
