• Record outburst of OT 081 (4C +09.57, PKS 1749+096) detected on July 16 with daily flux 3.9e-6 (70 times the 3FGL catalog averaged flux) and with 6-hour interval peak flux of 7.0e-6. Daily flux 2.4e-6 on July 17.
• Flare of 4C +01.02 (PKS 0106+01) detected on July 14 with daily flux 2.3e-6 (18 times the 3FGL catalog averaged flux). It is detected in high state (>1.5e-6) in the other days of the week.
• First strong flare of PKS 0403-13 (z=0.571) detected on July 11 with daily flux 1.6e-6 (140 times the 3FGL catalog averaged flux). Daily flux 1.3e-6 on July 12 (see ATel#9242 for more details).
• TeV blazar 1ES 1959+650 active during the week, peaking on July 12 with daily flux 0.5e-6.
• PKS 1256-220 detected all week. Flaring activity is observed on July 12 with daily flux 0.8e-6 (24 times the 3FGL catalog averaged flux).
• 3C 454.3 with daily fluxes between about 1.7e-6 (on July 16) and 3.8e-6 (on July 11).
• CTA 102 with daily fluxes between about 0.7e-6 and 1.5e-6.
• PKS 0502+049 in high state with daily fluxes between about 0.7e-6 and 0.9e-6.
• PKS 0426-380 with daily fluxes between about 0.5e-6 and 0.9e-6.
• Gravitational lens B0218+357 (S3 0218+35) detected on July 12 at 0.3e-6.
• Preliminary unassociated detection ASP J132608-054322 on July 12. The candidate gamma-ray blazar PKS B1324-047 (TXS 1324-047, CGRaBS/CRATES/BZcat catalog source, z=1.8820) is within 1 degree of the gamma-ray position.

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.
