Thank you for your pictured coverage, Satori! ;-)
All seems to be gone well so far.

Remember that this is a 9 hour + mission so spacecraft separation is still far away...!

ILS blog now reports mission success http://www.ilslaunch.com/nimiq-5-mission-success/

Quote

We have had confirmation that the satellite separated from the vehicle on schedule at 12:34 AM EDT, or 04:34 GMT, 9 hours and 15 minutes after liftoff.

Congratulations to ILS and the Proton team.

Nice! Congratulations to the teams for another successful Proton-launch!

Attached is a video of the Nimiq-5 launch preps, recorded during the ILS launch broadcast

According to the mission profile detailed on the ILS web site, the Nimiq 5/Briz-M combination should have entered a 49.1 deg, 415-35,796 km transfer orbit.

USSSN has issued the first element set from this launch under 2009-050A/35873, and this shows the following transfer orbit: 49.40 deg, 370.48 minutes, 341-21,078 km.

So, could there have been an underburn of the fourth Briz-M ignition? Or does this lower-apogee orbit represent some intermediate orbit? The tracked orbit does not obviously equate with the pre-launch profile, but I see that ILS have declared the launch a success.

Well, everybody seem to take it for granted but I'd like to emphasize that Baykonur launched yesterday two large rockets, Soyuz-2 and Proton-M, in less than four hours. Don't know if this is a record but I think nobody in the world can repeat the feat.

Launches within 24 hours are more often, e.g. Progress M-57 and Kosmos-2421 in 2006 (13 hours apart) and Progress M-66 and Express-AM44 last February (18 hours apart).

According to the Khrunichev online flight data resource http://coopi.khrunichev.ru/download/2009/nimiq5/email/rus/nim5_e09.htm, the scheduled orbit was 13.0°, 9491x35786 km and the actual orbit matches this within 7 arc seconds and 250 meters (not *kilo*meters).

USSSN has issued the first element set from this launch under 2009-050A/35873, and this shows the following transfer orbit: 49.40 deg, 370.48 minutes, 341-21,078 km.

That's Briz-M tank, I think.

I certainly hope so!! For some reason the ILS profile never lists the planned separation orbit of the tank, although I believe that it is given in the Khrunichev press kits which I can never find online ..........
