  • Sporadic activity (fluxes below 1.0 X 10-6) observed from PKS 1124-186 (0.6 on Nov. 3 and 0.7 on Nov. 5), B2 1520+31 (0.5 on Nov. 4 and 0.2 on Nov. 5), PKS 0301-243 (0.2 on Nov. 2), PKS 0524-485 (0.4 on Oct. 31), OG 050 (0.6 on Nov. 5), AP Lib (0.8 on Nov. 4), and Mkn 501 (0.4 on Nov. 3)



Fluxes are in the units 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.
