Four stars (about 1m - 3m) and one planet <br /> (brighter than 2m) are missing in this chart. In the chart, the distance from the centre <br /> is in proportion to zenith distance<br /> <br /> (1) (20 points) Draw a cross (X) on the location of each missing star and mark “T” on <br /> the chart, and draw a cross (X) on the location of the missing planet and mark “P” on <br /> the chart.<br /> <br /> (2) (5 points) Please mark the orientation of the star chart with “N” “E” “S” “W” at <br /> the edge of the star chart.<br /> <br /> (3) (10 points) On the chart, the celestial equator passes through many constellations. <br /> Please write down the name of any five of these constellations (IAU codes).<br /> <br /> (4) (5 points) Using the star chart, estimate the altitude of Aldebaran (α Tau), to the <br /> nearest degree.<br /> <br /> ==中文题目==<br /> <br /> 观测第一题（40分）<br /> <br /> 图一是今晚（大约为11月7日 小编记不得了）北京延庆8：30（UTC+8时区）一幅极限星等为5等的星图。<br /> 图上四颗1-3等的恒星和一颗亮于2等的行星丢失掉了。在本图中，到中心的距离与天顶距呈正比例关系<br /> <br /> （1）（20分）在星图上丢失的恒星的位置画X并且在旁边标上“T”，并在丢失的行星的位置画X并且在旁边标上“P”<br /> <br /> （2）（5分）请在星图边缘用“N”“E”“S”“W”标记星图的方向。<br /> <br /> （3）（10分）在星图上，天赤道经过许多星座。请写下其中五个星座的名字(用IAU代码)。<br /> <br /> （4）（5分）使用星图,估计毕宿五的高度(αTau),精确到度。</div>
