[beidou]

Continued BeiDou launch with dual-MEO.

[Satori]

Possibly the next Beidou-3 launch after M5 and M6.

Possibly the next Beidou-3 launch after M5 and M6.

Likely in early Sept.

[beidou]

Now there is information saying this will be on Aug 25th.

[input~2]

The same information indicates CZ-3B/YZ-1 as expected and not CZ-3C/YZ-1

[Alter Sachse]

The same information indicates CZ-3B/YZ-1 as expected and not CZ-3C/YZ-1

CZ 3B/YZ 1 was the version used for the previous double launches.

[Liss]

Shoud be the second launch to Plane C, PRNs C29 and C30.

This I believe is for the BDS launch after this pair.

This might be for the next pair (M13/14) after this launch......because we now get NOTAMs for this one and it's indeed on August 25 (LT)!

Please note this mission lasts about four hours to deploy and the forum will be down around that time confirmation of S/C Sep is expected:

https://forum.nasaspaceflight.com/index.php?topic=46224.0

So be aware that NSF may not be back until about 7 AM UTC.

[Galactic Penguin SST]

T-0 is apparently at 23:53 UTC (this is a "breakfast launch" so local reports should be plenty  ).
Launch code is 07-92.

[Galactic Penguin SST]

There's audio confirmation of a launch occurring. 

[Chris Bergin]

There's audio confirmation of a launch occurring. 

Let me know if that's good enough to put on the article or if we need more. Saw your "confirmation" tweet, thanks! Also, with the forum downtime later, can you all please tweet any launch images (I know they will come no sooner than four hours time) and tag @nasaspaceflight with them as the news site will stay up and I can add one to the article. And then post them here when the forum returns. Thanks!

Сичан /пров. Сычуань/, 25 августа /Синьхуа/ -- В субботу Китай с помощью ракеты-носителя "Чанчжэн-3Б" /серия "Великий поход"/ вывел на орбиту два навигационных спутника "Бэйдоу-3".
Это 11-й и 12-й спутники, запущенные Китаем для спутниковой навигационной системы "Бэйдоу-3".
Запуск был произведен сегодня в 07:52 по пекинскому времени с космодрома Сичан в юго-западной китайской провинции Сычуань. После более чем трехчасового полета спутники успешно вышли на заданные орбиты.
Новые спутники разработаны и изготовлены НИИ инновационных разработок микроспутников при Академии наук Китая.

Is there any information about the serial numbers?

CZ-3B ...
YZ-1...

Also looking for this. (Best guess is Y50 and Y9 based on sequence of earlier Beidou flights but would be nice
to get confirmation)

Objects are 43602-43605
Two objects with TLEs so far, one in the target orbit 21532 x 22193 km x 55.0 and one which must be the third stage in
a 192 x 18630 km transfer orbit

Shoud be the second launch to Plane C, PRNs C29 and C30.

I meant C25 and C26 of course.

[Liss]

43603 has already stabilized itself at C-8, 43602 continues towards C-6.

[Liss]

The latest elset for 43602 shows orbit change on approach to position C-2.
