Covered period: 2012.September.17 - 2012.September.23
LAT Mission week: 224.57 - 225.57
- The gravitationally lensed blazar S3 0218+35 detected in high activity on September 17, 19, 20, 21, and 22 with a daily flux between (4.5±0.5) X 10-6 and (1.8±0.3) X 10-6. Fermi LAT Target of Opportunity pointing observations are scheduled between 2012 September 24 and September 30 to detect the potential echo. See ATel#4411.
- PKS 0458-02 detected in flaring activity on September 17 with a daily flux (1.0±0.3) X 10-6. See ATel#4396. Follow-up observations confirmed the high activity of the source in optical (see ATel#4402) and in X-rays (see ATel#4407).
- CTA 102 detected in high activity on September 17, 19, 20, 21, 22, and 23, with daily flux between (6.1±0.5) X 10-6 and (0.9±0.3) X 10-6. See ATel#4409.
- OJ 248 detected in flaring activity on September 23 with a daily flux (1.1±0.3) X 10-6. See ATel#4421. The source was also detected on September 21, with a daily flux (0.4±0.2) X 10-6.
- PKS 1424-41 detected on September 17, 20, 21, 22, and 23, with daily flux between (1.2±0.4) X 10-6 and (0.6±0.2) X 10-6.
- 4C +38.41 detected on September 17, 20, 21, 22, and 23, with daily flux between (1.7±0.3) X 10-6 and (1.0±0.2) X 10-6.
- Mkn 421 detected on September 19, 20, 21, 22, and 23, with daily flux between (0.5±0.2) X 10-6 and (0.3±0.1) X 10-6.
- PKS 2233-148 detected on September 19, 20, 21, and 22, with daily flux between (1.0±0.2) X 10-6 and (0.4±0.1) X 10-6.
- PKS 2326-502 detected on September 20, 21, and 23, with daily flux between (0.6±0.2) X 10-6 and (0.3±0.1) X 10-6.
- Sporadic daily detections of blazars (fluxes below 1 X 10-6): PKS 0116-219 (September 17), B3 1343+451 (September 19, and 20), PKS 0244-470 (September 21), PKS 0250-225 (September 22, and 23), NGC 1275 (September 23).
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.
