说明: 这颗新彗星相当上相。上星期在瑞典．摩尔比古堡 (Mörby Castle)遗址，拍摄三个月前刚发现的爱喜彗星时，见到它有个泛着绿晕的彗发而且拖着长达数度的彗尾。对彗星观察者来说，过去数週真是忙碌，因为同时出现了四颗双筒望远镜可见的彗星，分别有艾桑、爱喜 (Lovejoy)、恩克 (Encke)和丽霓儿 (LINEAR)。其中，爱喜彗星 (C/2013 R1)从幽暗地区观看正处于肉眼可见的阶段。由于新月(农曆初一)出现在星期一，接下来月光干扰较少的这几天，是观赏达到最大亮度的爱喜彗星之好时机。在二个半星期内，爱喜彗星将运行到最靠太阳的位置，届时，它刚好在地球道距离之内。

Explanation: This new comet is quite photogenic.Comet Lovejoy, discovered only three months ago, was imaged through ruins of ancient M�rby Castle in Sweden last week sporting a green-glowing coma and tails trailing several degrees.The past few weeks have been an unusually active time for comet watchers as four comets were visible simultaneously with binoculars: ISON, Lovejoy, Encke, and LINEAR.C/2013 R1 (Lovejoy) comet is currently visible to the unaided eye from a dark location.As Monday's new Moon will provide little glare, the next few days provide a good time to see Comet Lovejoy as it reaches its peak brightness.In two and a half weeks, Comet Lovejoy will reach its closest approach to the Sun at a distance just inside the orbital distance of the Earth.
