Residents of east asia saw the eclipse cut short by moonset , while those in the eastern parts of north and south america had the moon already partially or totally eclipsed by the time it rose over the horizon in the evening 東亞的居民在看見月蝕的時候月亮已經快要下山了,而相反住在美洲東南部或者東北部的居民在月亮升起的時候月蝕就已經經歷了一段時間了。

Weather permitting , the penumbral eclipse can be observed by local residents for a short time interval before the moonset that morning 若天氣情況許可,香港市民可在清晨月落前短暫時間觀賞到此天象。
