Here is an official announcement for SJ-12, "soon to be launched" dated to-day at 11:45 UTC; usually this type of announcement is published around one day in advance, so launch will probably occur tomorrow June 15

Heh, the orbit is close to Shiyan weixing 1 (2004). A follow-on?

That's about 23 minutes after you posted it. I think you mean local.

How is the orbit relativ to Shijian 7?

Different planes. SJ-7 passes descending node at 05:05 or so while SJ-12 passes at 07:58.

Thank you Liss. At the moment we only know that SJ-12 was built by the Shanghai Academy (SAST), i.e. the same manufacturer as for SJ-7, whereas SY-1 was built by Harbin Insitute of Technology. Both SJ-7 and SY-1 seems to have been used for observation and tracking of the Asat test in January 2007.  There are rumors at 9ifly that SJ-12 could have IR-sensors on board.

Yes, if we speak about platform/payload builders SJ-12 looks much more like SJ-7 than SY-1.

On August 13, after intentional maneuvering, SJ-12 passed close to SJ-6F (2008-053B).

By Aug 13, SJ-12 set to precede SJ-6F by 160 km.
By Aug 15, it took a closer position at 27 km or so.
It is possible that today or tomorrow we'll see final approach.
