Update #12
As of 10:30 p.m. EDT on Sept. 23, 2011, the orbit of UARS was 85 miles by 90 miles (135 km by 140 km). Re-entry is expected between 11:45 p.m. Friday, Sept. 23, and 12:45 a.m., Sept. 24, Eastern Daylight Time (3:45 a.m. to 4:45 a.m. GMT). During that time period, the satellite will be passing over Canada and Africa, as well as vast areas of the Pacific, Atlantic and Indian oceans. The risk to public safety is very remote.
大致翻译如下：
美国东部时间23日晚上10：30（也就是北京时间今天24日上午10:30），卫星距离地球135-140KM（上一次更新是3个小时前，当时距离地球145-150，也就是说每3个小时下降10KM，这个速度会越来越快，进入100到80KM才是好戏）预计会在北京时间 11点45 到 12点45 返回地球，经过地区：非洲，太平洋，大西洋，印度洋
如果我们想看到，只有卫星在印度洋的时候，往西南靠南方向才有可能看到表演。
新疆，西藏，云南应该可以看到的更多
