我国今年将发射两颗风云气象卫星 (https://finance.sina.cn/2023-02-22/detail-imyhprua8576531.d.html)
my country will launch two Fengyun meteorological satellites this year
The Fengyun-3F star is expected to be launched in August. As a satellite in morning orbit, the satellite will take over the in-orbit business of Fengyun-3C. On the basis of ensuring global imaging of polar-orbiting meteorology and vertical atmospheric detection, the satellite will focus on imaging observation of the earth's surface, mainly used in weather forecasting, ecological environment, and disasters. Monitoring and other operations and research. The Fengyun-3 F star is equipped with 10 payloads, 2 of which are newly developed, and 3 of which are upgraded.
The last FY-3E was launched from Jiuquan in 2021, though before that past FY-3s were launched from Taiyuan.

There is a launch on Augest 4 from Jiuquan.

风云三号06星通过出厂评审，预计将于今年8月发射 (https://www.nbd.com.cn/articles/2023-06-09/2865325.html)
The Fengyun-3F passed the factory review and is expected to be launched in August this year
Every AI newsletter, China Meteorological Administration official Weibo news on June 9th, on May 31st, the 06-star Fengyun-3 factory review meeting was held in Shanghai. After listening to the factory review report of Fengyun-3 06 star, the participating experts said that the development and testing of the star and its payloads had all been completed and met the factory conditions, and they unanimously agreed to pass the factory review.
Fengyun-3F is the third satellite of Fengyun-3 03 batch of satellites. It belongs to the morning orbit satellite and is expected to be launched in August this year. After its successful launch and in-orbit operation, it will take over the in-orbit business of Fengyun-3C. . On the basis of ensuring the global imaging observation and atmospheric vertical detection of low-orbit meteorological satellites, the star focuses on atmospheric quantitative detection and climate change monitoring. The data are mainly used for weather forecasting, atmospheric chemistry and climate change monitoring operations and research.
This should be launched in Augest.

The NOTAM from Jiuqan for CZ-4C Fengyun-3F, because Fengyun-3E was luanched on July 5, 2021. (https://forum.nasaspaceflight.com/index.php?topic=57867.msg2502509#msg2502509)

If you go to the 10:10 LTDN plane (as FY-3C did), you'd launch at 11:55 BJT = 03:55 UTC.

The China NOTAM will be more accurate, wait for end of this month.

I agree this one might be FY-3F since it's supposed to replace FY-3C in the "morning orbit" and the launch time looks right for that.

There is still no any NOTAM from ZLHW until now, I am adoubt this launch maybe will be delayed.

PLA Strategic Support Force always has the best view of a rocket launch in China, but they often add unnecessary music.
Do you like the music better, or pure rocket engine roaring?

JIUQUAN, Aug. 3 (Xinhua) -- China on Thursday launched a satellite into space from the Jiuquan Satellite Launch Center in northwest China.
The Fengyun-3 06 satellite was launched at 11:47 a.m. (Beijing Time) by a Long March-4C carrier rocket and successfully entered the planned orbit.
The launch marked the 481st flight mission of the Long March series carrier rockets.

There was a presentation. Sorry for the postage size grabs, but the camera was zoomed quite a bit out.
-
Second stage ignition was expected at T+20:18 with cutoff 35 seconds later at T+20:53. Here's some grabs of the burn. Again, camera was zoomed out.
-
Separation occurred during the presentation! Only the last grab was shown near full screen.
-
Here are the slides that were shown during the second ignition and spacecraft separation. The last slide is the sequence of events.

Looks like the upper stage is doing a yaw maneuver. The satellite is at bottom left and is about to go out of view.

"0347:47 UTC seems to be T-0"
this is probably the time of ignition
03:47:51 could be liftoff
or 03:47:50 (pic 2)

Radio obs confirm that 57492, 2023-111C is indeed a satellite
http://OrbitalFocus.uk/2023#110
Signal characteristics are similar to Yaogan 21 and, as I pointed out earlier, the two satellites’ orbits are co-planar

I suspect that this is a mis-identification with this launch, because we have seen in the webcast that there's no place for this rocket to place something else in a completely different SSO (IIRC CZ-4C has only one restart capability). It may very well be a satellite, but it probably has nothing to do with 2023-111.
