There seems to be a second drop zone just off the coast of Myanmar that is related to this launch, which would make this a CZ-4 series launch if I am not mistaken.
At 11:41 AM Beijing time on December 9th, my country successfully launched the Yaogan-47 satellite into its predetermined orbit using a Long March-4B carrier rocket from the Jiuquan Satellite Launch Center. The launch mission was a complete success. This satellite will primarily be used for national land surveys, urban planning, road network design, crop yield estimation, environmental management, and comprehensive disaster prevention and mitigation.This mission marked the 614th flight of the Long March series of carrier rockets.北京时间12月9日11时41分，我国在酒泉卫星发射中心使用长征四号乙运载火箭，成功将遥感四十七号卫星发射升空，卫星顺利进入预定轨道，发射任务获得圆满成功。该卫星主要用于国土普查、城市规划、路网设计、农作物估产、环境治理和综合防灾减灾等领域。此次任务是长征系列运载火箭的第614次飞行。
