Khrunichev information about the launch:The Inmarsat-5F1 mission will be the ninth Proton launch of 2013 and the 392nd Proton flight overall.
This will be the seventh commercial mission of the year for ILS and the 84th ILS Proton mission since the Proton April 1996 first commercial flight.
This will also be the 3rd Inmarsat satellite launched with Proton. In addition, the Inmarsat-5F1 will be the 16th Boeing satellite launched on Proton.
The upper stage follows a five-burn injection profile.
The first burn occurs 94 seconds after the Breeze-M separation from the launcher, forming a parking orbit.
The second ignition is performed in the second descending node of the parking orbit, resulting in an intermediate orbit. The third main engine (ME) burn occurs at the intermediate orbit perigee in an descending node. The ME ignites for the fourth time 137 seconds after the third ME cutoff. The third and fourth ME burns form a transfer orbit with an apogee close to that of the target orbit. The additional propellant tank is jettisoned between the third and the fourth ME burns. The fifth ME burn is performed at the transfer orbit apogee in a ascending node, placing the OU into the target orbit.
The lnmarsat-5F1 satellite is released 12 minutes and 26 seconds after the final ME burn.
The lnmarsat-5F1 injection from liftoff to separation is completed in 55,860 seconds, or 15 hours, 31 minutes and 00 seconds.

Proton M at Fueling Station Now
It should take several days to complete fueling operations and then the ILV should be moved to the Launch Pad.
Thanks for sharing.
Q: where to refer fuel operations in some detail? Any video(s) or illustrations?

OK, not as rare as I thought purely from memory, but still rare. :-)
They seem to be getting more frequent, or perhaps with the start of SpaceX super-sync GTO missions they are simply getting more attention in the United States. I tried to calculate the goodness of the SES-8 delivery orbit:
and my result was a (close) over-estimate of the nominally required delta-v. Musk claimed 1500 m/s and my technique generated 1510.
FWIW using the 4,341 x 65,000 x 26.75 values published for the INMARSAT-5 F1 target orbit, my technique generates 1,475 m/s of delta-v to reach a geostationary orbit. Has ILS published a "delta-v to GEO" value anywhere?

The commercial standard for GTO missions is to leave the payload within 1500 m/s of GEO. Note that this 1500 m/s can be either in terms of orbital height, or inclination difference, or some combination of both.
Having a commercial standard for GTO allows launchers to be compared on an "apples to apples" basis, although other factors in evaluating launchers do apply.
