Several local tour operators are currently advertising for a LM-3B Xichang launch on January 19, curiously stating that it's of a Tianhui series satellite. That's highly interesting because the series of cartography satellites doesn't seems likely to involve BLEO operations.Either the tour operators got it wrong, or there's another LM-3B SSO launch soon, or (one theory from Chinese forums) it's the long rumored/reported Chinese geosynchronous SAR satellite. (note that SAR requires the antenna to be moving to work, so geostationary orbit won't work and people assume it would go to an inclined GSO)
According to a post on 9ifly Chinese space forum, the rocket to be used is a CZ-3B/G3 with serial number Y77 and the payload is the 20-meter L-band SAR Tianhui-3 satellite to operate in GEO.
A few launches reported (at some time) to take place in February:<snip>- Tianhui-3 (?) to be launched (?) by a Chang Zheng-3B/G3 from Xichang;<snip>

Spaceflightfans.cn has a CZ-3B launch on July 6 but is not listing the payload.<snip>
Spaceflightfans.cn is giving July 6 (TBC) as the launch date for Tianlian-1 (05).
