We are now at 10 minutes from the schedule launch time.

If everything went according to plan, the Proton-M/Briz-M with the Globus-1M (13L) satellite should be lifting-off from Baikonur at this time.

Scanning the Russian news agencies for news about the launch.

RIA Novosti is reporting that launch took place!

Following the same pattern of a ILS commercial launch, this mission should be a 9 hour plus long flight.

Thanks Rui! Good to hear that went well for the launch phase.

Citing my article on AmericaSpace.com, I understand that this will be a 5-burn Briz-M mission, of very similar design to the Sirius FM-6 mission.

And we have confirmation of the separation of the Briz-M with the Globus-1M sat.

Thank you, Rui!
It seems, that all was nominal.

Perhaps we will see some pictures of the rocket and the launch.

Interesting statement that the payload has L, C, X and Ka-band. I don't think I've seen this information on Raduga-1M
before.

This is consistent with the 2010 launch and suggests a 4-burn, not 5-burn, profile is being used:

 - burn 1 to  170 x 170 km
 - burn 2 to 270 x 5000 km
 - burn 3 to 400 x 35600 km, followed by DTB  (APT) separation
  - burn 4 to GEO

When 5 burns are used, DTB is usually in a lower apogee orbit.

However, the transfer inclination is 48.6 deg instead of 46.5 deg used in 2010.
The 2007 launch used a 5 burn profile (with DTB in 17660 km apogee orbit) and a 49 deg transfer orbit.
So, each of the Raduga-1M/Briz launches to date has used a different profile!

Yes, four burns:

"Дальнейшее выведение космического аппарата на целевую орбиту будет осуществляться с помощью четырех включений двигателей разгонного блока "Бриз-М". Ожидается, что на это уйдет девять часов", - сообщил "Интерфаксу-АВН" официальный представитель управления пресс-службы и информации Минобороны по войскам ВКО полковник Дмитрий Зенин.

Perigee of the DTB/APT transfer orbit was at 0325 UTC, which is right on the expected timeline by comparison with the 2010 launch. Apogee is at 0840 UTC, 7 min before spacecraft separation, a good time for the final burn.
