Mission details:

The YW 4 satellite (Remote Sensing Satellite No. 4) was launched from China's northern Jiuquan space center on Dec 1 into a 633 x 652 km x 97.9 deg orbit. As for YW 2, no launch vehicle stage was cataloged; it seems probable that the CZ-2D second stage makes a depletion burn after payload separation and reenters within a few orbits.
