The Chinese name is Fengyun-2-7.
AFAIU, it's called FY-2F rather than FY-2G since FY-2A was the second in the series.

Well, this is a CZ-3A, which has no boosters, so we have only one NOTAM for the fairing

Did anyone managed to catch any official information about this launch? Apart from the SZ-8, China is still not officially announcing the launches in advance.

Less than two hours from the predicted launch time; any news on the Chinese space forums?

Should launch any time now... Here's the launch pad at T-80 minutes.

Cool!!!! Let's wait for spacecraft separation...
Launched at?
Not sure, though I've seen a reference of 00:56 UTC...

USSTRATCOM has so far catalogued one object:
2012-002A/38049 in 351.7 x 35780.2 km x 24.31°
(epoch: Jan 13, 0503:22UTC)
This orbit seems different from the FY-2F orbit mentionned in the Xinhua release (211 x 36139 km x 24.4°)

This orbit seems different from the FY-2F orbit mentionned in the Xinhua release (211 x 36139 km x 24.4°)
It can take a day or two for the USSTRATCOM orbital data to settle down to a representative set of figures.

We now have object B:
- 2012-002B/38050 in 224.3 x 35941.0 km x 24.31°
(epoch Jan 13, 0757:41UTC)
somewhat closer to the announced FY-2F initial orbit.
Object A would then be the CZ-3A 3rd stage (any reason for its 128km higher perigee?)

So China has the first and only two orbital launches in the year so far - probably a first.

(epoch Jan 13, 0757:41UTC)
somewhat closer to the announced FY-2F initial orbit.
The altitude of the apogee, 35941 km, is to be compared with the following information from the CZ-3A User's Manual:
The standard GTO is the baseline mission with following injection parameters from XSLC.
Perigee Altitude Hp 200 km
Apogee Altitude Ha 35,958* km
Inclination i 28.5 Deg
Perigee Argument ω 179.6 Deg
Note: * The parameters [above] represent the SC’s immediate orbit upon
separation, where Ha corresponds to the altitude of 35,786km when the SC arrives at its first apogee after a period of unpowered flight, taking into account the perturbation caused by the earth’s oblateness.

"During this time-lapse taken from the VLT complex at Paranal observatory, I caught an small sequence of a rare blurred object (0:14-0:18). The object is probably related to the launch of the FengYun-2F satellite from China (2012-01-13 at 00:56 UT), because is consistent with the moment when this object appeared in the sky (01:39 UT). The object turned fainter and vanished after some minutes.
P.S. Thanks to Douglas Pierce-Price for your help in identify this object!"

Just an observation from looking at the ground track using latest TLE's - these two spacecraft spend moist of each orbit over parts of the Earth that are in darkness. Bit odd for a metsat - if observing in visible light ? But, track does take it over most of the troubled military 'hotspots' .

This is just a temporary transfer orbit. In a few days the payload will transfer to geostationary orbit where it stays above China (and will be in darkness exactly 50 percent of the time - annually averaged - , just like China!)
This is a totally standard orbit insertion for a geostationary metsat, no need for paranoia.

Looks now like USSTRATCOM has switched Object A and Object B.
Old "A" is now "B" (ie 3rd stage)
To be confirmed

Confirmed:
Object A (FY-2F) is now nearly geostationary at 111.8°E in 35745 x 35813 km x 2.40° (epoch Jan 19 at 0356UTC)
- Object B (CZ-3A 3rd stage) remains in 369 x 35783 km x 24.36° (epoch Jan 18 at 1254UTC)
