China orbited a new weather satellite, named Fengyun 3B (FY-3B), on November 4, 2010.  A Chang Zheng (CZ) 4C carried the 2.299 tonne satellite into sun synchronous orbit from Taiyuan Satellite Launch Center's second launch pad.  The three-stage rocket lifted off at 18:37 UTC.  FY-3B entered its 800 km x 98.7 deg orbit about 19 minutes later.

FY-3B joins FY-3A in orbit.  FY-3A was launched on May 27, 2008.
