The longitude and <br /> latitude of the observation site is 120°E, 40°N (UTC+8). The grid in the figure is an <br /> equatorial grid. The thicker vertical line in the centre is the meridian. Estimate the <br /> mean solar time to an accuracy of better than 0.5h.<br /> <br /> ==中文题目==<br /> <br /> 观测第三题（20分）<br /> <br /> 图3是2018年3月21日部分天空的星图。观测点经纬度分别为120°E、40°N (UTC+8)。图中的网格是赤道坐标。中间较粗的垂直线是子午线。估计平太阳时，精度要好于0.5小时。</div>
