由太阳周日视运动规律易知,当太阳直射北半球时,全球太阳东北升西北落,北半球日出时间(地方时)早于6:00。同理,当太阳直射南半球时,全球太阳东南升西南落,南半球日出时间(地方时)早于6:00。地方时6:00的太阳方位自然成为一个人们关注而又困惑的问题。由于太阳直射赤道时,全球太阳正东升正西落,且各地日出时间均为地方时6:00。因此,不少人错误地认为:夏半年,太阳日出东北,北半球日出时间早于6:00,那么经过一段时间的运行,
As the sun observes the law of daytime movements of the sun, when the sun is directing the northern hemisphere, the global sun rises northeast to northeast, and the northern hemisphere sunrise time (local time) is earlier than 6:00. By the same token, when the sun is directed at the southern hemisphere, the global sun rises southwestwards in the southeast, and the sunrise time in the southern hemisphere (local time) is earlier than 6:00. The natural orientation of the place at 6:00 naturally became a matter of concern and confusion. As the sun directly reaches the equator, the global sun is rising eastwards and the sunrise time is 6:00 am. Therefore, many people mistakenly believe that in the summer half year, the sunrise of the sun in the northeast and the sunrise in the northern hemisphere will be earlier than 6:00. After a period of operation,
