And it's an official launch success! Launch occurred at 03:26 UTC.
BTW Chris, the payload's a civilian Earth observation satellite (it's main user is the Ministry of Land and Resources), unlike the last few ones from Taiyuan. The payload's mass was given as 2100 kg, and the satellite is designed for a 3 year service life.
The CBERS satellites were around 1,450 kg, so this must be a significant upgrade if it's 2,100 kg or so.
CBERS-2B (ZY-1 02B?) introduced the 2.5m pan camera. This one doubles that up and replaces the wide field imager with more fairly high res (5 and 10m resolution) cameras. So that's consistent with a fair upgrade.

Hi-res launch pics for a high-resolution remote-sensing satellite(!)
I'm *really* enjoying close-up looks at launchers I've only ever seen teeny weeny postage-stamps of in the past. The Chinese space program is starting to come to life for me
What has prompted this sudden, unexpected - and very welcome - change of heart? Dare I be cynical and relate it to the shuttle being killed off? Let's hope someday we'll see early launches in the same way.

To re-post a question from earlier that interested me: what is the US record for launches in a year?

As my usual nitpicking of the article:
The rocket is capable of launching a 2,800 kg satellite into low Earth orbit, developing 2,960,000 kN at launch
Are you sure those are kN? Seems a bit high

That's a really powerful rocket!!!
Its 2,971 kN.

I have 73 (Cape Canaveral - 29; Vandenberg - 43; Wallops Island - 1) in 1966.

And of course, China has overtaken the United States of America
in satellite launches.

Ok, this one is strange. Why the Brazilian flag if there was «no Brazilian participation» on the mission?

Is it for CBERS 3? That would be the 6th ZY-1 .........

It is a satellite developed by China and Brazil.

I had the opportunity to hear about this "CBERS-2C" in a talk some months ago. Knowing that there was no Brazilian participation on this particular satellite I asked the presenter (from CEODE) why the "CBERS" name was used. He smiled and said that that is the way they translate 'ZiYuan' for international presentations, and there was a lot of 'paperwork' to be done if a new name was used.
That maybe explains the Brazilian flag... did they use the same 'marketing' material just replacing 2B by 2C?

This is not CBERS 3. I suspect that it uses the same panchromatic camera though, from what I read from the specs.

Images from China TV (http://vod.mlr.gov.cn/spxw/201112/t20111229_1051742.htm) indicate a slightly different design of ZY-1(2C) - 2 solar arrays.
Not sure if this is meant to be a true representation of ZY-1-2C.
There are many references pointing to a one-wing only solar array for this S/C.
