It was the 100th Proton-M and the 414th Proton launch since 1965.
In my list the 413. launch.
Roskosmos counts possibly the accident of the 14.07.1968.

DTB tank cataloged as 42908 in 399 x 35698 km x 48.6 deg transfer orbit. Suggests a 4 burn launch profile.

Blagovest reaches intended orbit

ISS-Reshetnev Company’s new telecommunications satellite, Blagovest, which was launched on August 17 has finally arrived at its position at the geostationary orbit.

Upon arrival at the intended orbit, Blagovest’s mechanical systems, including its solar arrays and antennas, were successfully deployed. The satellite completed Sun acquisition and transmits all the necessary telemetry to the ground. When the satellite performs Earth acquisition ground specialists will begin checking out the performance of all its systems.

Blagovest №11 was designed and built by ISS-Reshetnev Company around its heavy-class Express-2000 platform. It is the first satellite which is equipped with a payload fully developed and constructed by the company on its own. Blagovest is intended to provide high-speed Internet access, data communications, television and radio broadcasting, telephony and videoconferencing services using increasingly attractive Ka and Q frequency bands.

I thought that the Briz M tank usually separated between the 2nd and 3rd burns during a 4-burn ascent.  Wouldn't that leave the tank with a sub-GEO apogee?

Apologies but going off-topic here.

Is there an online source which gives the number of Briz-M burns planned for the domestic (non-ILS) missions, please?

Thanks!

Drifting 1.9°E per day, near 60°E now.
Apparently not (yet) aiming for 45°E.

Then it drifts up to 128° E ?
