&lt;p&gt;&lt;b&gt;新页面&lt;/b&gt;&lt;/p&gt;&lt;div&gt;==英文题目==&lt;br /&gt;
&lt;br /&gt;
TASK 5: NAKED EYE BRIGHTNESS ESTIMATION&lt;br /&gt;
&lt;br /&gt;
available time: 5 minutes &lt;br /&gt;
&lt;br /&gt;
5 points&lt;br /&gt;
&lt;br /&gt;
• Estimate the visual magnitude of the two naked-eye stars marked on the stellar chart of &lt;br /&gt;
constellation Ursa Minor:&lt;br /&gt;
&lt;br /&gt;
a) ζ UMi (zeta UMi = Alifa) – STAR 2 &lt;br /&gt;
&lt;br /&gt;
b) γ UMi (gamma UMi = Pherkad) – STAR 1 &lt;br /&gt;
&lt;br /&gt;
c) Write your estimate with one decimal accuracy (e.g. 8.6).&lt;br /&gt;
&lt;br /&gt;
• Estimate the angular distance between γ UMi (STAR 1) and Polaris in degrees.&lt;br /&gt;
&lt;br /&gt;
==中文题目==&lt;br /&gt;
&lt;br /&gt;
任务5:肉眼亮度估计&lt;br /&gt;
&lt;br /&gt;
可用时间:5分钟&lt;br /&gt;
&lt;br /&gt;
5分&lt;br /&gt;
&lt;br /&gt;
•估算小熊座星图上标记的两颗裸眼可见的恒星的星等:&lt;br /&gt;
&lt;br /&gt;
a) ζ UMi (zeta UMi = Alifa) - 二号星&lt;br /&gt;
&lt;br /&gt;
b) γ UMi (gamma UMi = Pherkad) -一号星&lt;br /&gt;
&lt;br /&gt;
c)估算精确到小数点后一位。&lt;br /&gt;
&lt;br /&gt;
•估算γ UMi(STAR 1)与北极星之间的角距离(以度为单位)。&lt;/div&gt;</summary>
