Though not confirmed, this has been expected as the first Chinese launch in 2014.

I wonder if
this is related?

These drop zones are the same as those for Shi Jian 11-05 launched with CZ-2C on July 15, 2013; so it does look like a new launch with CZ-2C from Jiuquan on March 31
Indeed the launch time and drop zones are suggestive of this being the launch of SJ-11-06 (in fact a launch time of 02:45 UTC - 5 minutes before the Dragon was supposed to go - would be just right for launching into the plane of SJ-11-01,
now into its fifth year of operations and is probably beyond its lifetime).
The problem is, of course, there is no direct evidence this time (not even indications of CALT/CAST people working at JSLC right now!)........

I seem to remember a two launchers arriving simultaneously in early November 2013, but did not fly at the end of 2013, so it is probably still there.

Still no direct confirmation of any launch happening....... whoops.
Regardless it does seems to be worth watching if anything happens...

From Xinhua in English:
China launches experimental satellite
China successfully launched an experimental satellite into preset orbit from Jiuquan Satellite Launch Center in its northwestern gobi desert on Monday morning.
The Shijian-11-06 was boosted by a Long March-2C carrier rocket at 10:58 Beijing Time. The satellite, which was developed by China Spacesat Co. Ltd under the China Aerospace Science and Technology Corporation, will be used to conduct scientific experiments in space.
This was the 189th flight of the Long March rocket series.

Very good, thanks!
Rui's article:
http://www.nasaspaceflight.com/2014/03/china-open-2014-secret-satellite-launch/
I still don't see why some are characterizing this as "early warning". That's not done from a LEO orbit but rather from HEO/GEO.
If the comparison is to STSS, that's not early warning of missile launches but tracking and characterization. Very different:
http://www.mda.mil/global/documents/pdf/stss.pdfAnd even in that case, this is almost certainly not an operational system but rather a test & demonstration system (just like STSS). With only a few satellites in LEO, there's nowhere near continuous coverage of any particular region.

I think the launch of this satellite puts a pause on the "SJ-11 = C-STSS" theory - it seems strange for the Chinese to put up a STSS-esque early warning system without the addition of high orbit or geostationary satellites.
An alternative theory I have recently seen over the Chinese forums deduce that - given that the same chief designer of the SJ-11 (Li Yiandong) also worked on the YG-9 constellation and the SJ-9B series, and both worked in constellations on the surveillance role (SJ-9B probably on ELINT/radar and YG-9 on NOSS), searching on targets at unknown places (as opposed to the "reconnaissance role", filled in by the other members of the YG series), SJ-11 might turn out to be working in the wide angle optical/infrared surveillance role.
Any comments?

Yes, ISR is much more of a feasible role. Again, early warning is not feasible from LEO without many, many satellites. STSS is really providing tracking/characterization/targeting data on ballistic missiles, not serving an early warning function.

I wonder if there is a connection between SJ-11 and the JB-6 (YG-2/4/7/11) family of satellites.
Four JB-6 were launched in 2007-2010 into sun-synchronous orbits with LTDN (local time of descent node) 09:00, 11:00, 13:30 and 15:00. All the four maneuvered in December 2010 to the same altitude. YG-7 made another small correction in March 2013.
Six SJ-11 were launched in 2009-2014 into sun-synchronous orbits with LTDN 09:00, 10:45, 14:00 and 15:45. Looks similar, doesn't it? Small maneuvers were seen for #02 and #01, the latter on March 22, 2014.
I don't think SJ-11 is the follow-on system for JB-6 but it may be an addition with separate functions.

http://english.spacechina.com/n16421/n17212/c713592/content.html BEIJING, June. 23 (China Space News) — Shijian-11-06 satellite was delivered in-orbit to its user recently.
All indexes of the satellite had met the development requirements and some indicators better than the design requirements during the testing.
The customer has given high remarks on the development, launch and in-orbit testing of the satellite.
Now the satellite is operating stably in a good condition.
Regardless it does seems to be worth watching if anything happens...
