Need help with regards to reading the thread in the sticky https://forum.nasaspaceflight.com/index.php?topic=30673.0
There is a list of orbital launches there. Figured out most of the fields (please correct me if wrong) except the two fields coloured red. What does those two fields represent? I guess the second one is the launch timing, but what is the format...can't figure it out.
<sequence> <(99-99)> - <launch vehicle> <(factory serial no.)> - <launch date> <(9999:99.999)> - <launch site>, <launch pad> - <payload>
Btw, the (factory serial no.) is something i just made up. Another thread describe this as a factory number/serial number. What would be the correct descriptor for this number?

First field you question: The entry format for Chinese Launch authorization code as issued by the Launch Control Centre
Second field you question: The entry format for the full launch time minus the Day. International precise short time format is:
Julian Day or JDay (000 to 366) then Hour (00 to 23) then Minute (00 to 59) then Second (00 to 59) then Millisecond (000 to 999) Then ZULU Time (UTC) or LOCAL Time.
That is DDD:HH:MM:SS.MS ZULU or JD: 000:00:00:00.000 ZULU (alternate precise short format is 000:0000:00.000 ZULU).

Likely yes. I have checked the site with Sucuri, which confirms, that it has been compromised and could be harmful:

Someone has posted a Chinese paper that resolves all configuration discrepancies between the different rockets of the CZ-3A series. :)
Basically:
CZ-3A - just the one sub-variant
CZ-3B:
standard version - the original CZ-3B as flown in 1996, with standard length first stage and boosters, uses the 4.0 m diameter 4000F fairing
CZ-3B/G1 - standard version CZ-3B with the 3.7 m diameter 3700Z dual-payload fairing, only used for the dual COMPASS MEO launches in 2012
CZ-3B/G2 - the original enhanced CZ-3B, with lengthened first stage and boosters, uses the 4.0 m diameter 4000F fairing, first flown in 2007
CZ-3B/G3 - enhanced CZ-3B with the 4.2 diameter 4200F fairing
CZ-3B/G2 and G3 corresponds to what we call the "CZ-3B/E".
CZ-3C - currently just the one sub-variant, with standard length first stage and boosters, uses the 4.0 m diameter 4000F fairing (contradictory to what I said earlier, the CZ-3C as flown today do not use the lengthened first stage and boosters , but see below)
The problems with the different stage configurations (e.g. the pad at Xichang requires mating/de-mating of electric cables and gas ducts on the umbilical arms every time between launches of a CZ-3B/E and a CZ-3C) means that there's a need to standardize the launcher configurations. The "standard length" boosters will be phased out in the near future, leaving these mainstay sub-variants:
CZ-3B/G2 (GTO capability 5.5 tonnes)
CZ-3B/G3 (GTO capability 5.4 tonnes)
CZ-3C/G2 ("CZ-3C/E", or CZ-3B/G2 minus two boosters) (GTO capability 3.9 tonnes)
plus these special variants:
CZ-3B/G3Z - enhanced CZ-3B with the 4.2 m diameter 4200Z fairing and extra RCS tanks and thrusters on the 3rd stage, probably for extra-long coast missions. May debut on the Chang'e 3 launch later this year. GTO capability 5.2 tonnes.
CZ-3C/G3Z - CZ-3B/G2 minus two boosters. GTO capability 3.7 tonnes.
CZ-3B/YZ-1 - enhanced CZ-3B with the 4.2 m diameter 4200Z fairing and the planned GEO direct insertion upper stage (probably the one using RP-1/H2O2 fuel as exhibited in various aerospace exhibits over the past several years), will be used for future COMPASS system launches
CZ-3C/YZ-1 - CZ-3B/YZ-1 minus two boosters, will be used for future COMPASS system launches
Maybe someone can help to check which launch uses the sub-variants as described above? ;)

We all remember the Long March as a crucial moment in pre-1949 Chinese communist history because Mao Zedong and the Chinese communists saw the march as a sign how they could persist in the face of attacks by the Kuomintang. However, I've wondered why almost all Chinese carrier rockets are named for the Long March. Does anyone know who first suggesting naming China's rockets in honor of the Long March?

Its been a while since 2013 but there is reportedly development complete G4, G4Z, G5, and G5Z versions of CZ-3B and CZ-3C. CZ-3A upgrade programme appears to be frozen and possibly cancelled. Skyrocket has a reference to the standard G5 versions on his site but not much is known about the new versions.

Serial number is 1901H, so it is the first CZ-2D produced in 1991 and launched in 1992.

That was on 9.08.1992 (1992 Aug 9) with a FSW-2 satellite.

Another image of the same launcher from a souvenir enveloppe. I guess that the pictures were made during a launch excercise in 1992.

Here is the official explanation, but in Chinese. Basically it was suggested by the designers and approved by the leaders. The Long March 1 project started around the eve of the cultural revolution, they had very limited options naming it. Cannot use historical or mythical figure. East wind, red dawn is everywhere. Quoting poems of Mao seems a safe choice.
http://www.cnsa.gov.cn/n6758968/n6758973/c6771530/content.htmlNot all Chinese launch vehicles are called Long March. Feng Bao (Storm) was developed by Shanghai. It was a part of the power struggle between Beijing and Shanghai. Shanghai lost, so Feng Bao was no more.

I'm trying to find out which launch sites / pads in the JSLC area all the new privately developed Chinese rockets are currently using. Any idea which pas the following rockets use, what their official names are and where they are located?
- Ceres-1
- Kuaizhou-1A
- Kuaizhou-11
- Jielong 1
- CZ-11
- Shian QuXian-1 (Hyperbola-1)
- Zhuque-1
- OS-M1

There are 2 launch pads (about 5km NE of the known CZ-2/CZ-4 launch pads) which are used for the mentioned rockets. No confirmed designations for those launch pads are known. Based on some images from control center screens I guess that the launch pad for Ceres-1 is called No.95A. This would be in line with No.94 sometimes appeared in connection with the the CZ2/CZ-4 launch complex. And maybe the launch complex for CZ-2F is No.91. Based on designation No. 95A I assume that the neighbouring launchpad is called No.95B. This launch pad was used for KZ-1 launches in 2012 and 2013.
