On 2003 May 31, an annular eclipse of the Sun will be visible from a large
zone covering the North Atlantic. The path of the Moon's antumbral shadow
begins in northern Scotland, crosses Iceland and central Greenland, and ends
at sunrise in Baffin Bay (Canada). A partial eclipse will be seen within the

The first solar eclipse of 2003 is a very unusual annular eclipse which takes
place in the Northern Hemisphere. The axis of the Moon's shadow passes to the
far north where it barely grazes Earth's surface. In fact, the northern edge
of the antumbra2 actually misses our planet so that one path limit is defined

Explanation: Early on Saturday, May 31 (UT) the new Moon will once again slide across the
Sun's fiery disk, and once again an annular solar eclipse will be the result -- since the Moon's
apparent diameter will be a little too small to completely cover the Sun. But this time celestial

两个月后又收到它家的广告邀请，50K bonus points。于是抱着试试看的想法，按
voucher上链接和invitaion code，填了材料。虽然两周后收到据信，但是电话后还是
批了。visa regular， CL 2K。
现在是visa signature的annular fee 是$99,而visa regular的annular fee是$69。
虽然当时是冲着50k的bonus points去的，有些ws，但是同时hold两张SW 的rewards卡
还真的是没有必要。
想cancel一个，不知道visa signature card又什么显著的好处，一年多了$30 的年费
呢。记得似乎有在fandango上买电影票的优惠，印象不深？ |

发帖数: 780 | 8 自然是 FEI的 titan， 配20kv mode， 然后还有cs corrector, 加上 High-angle
annular dark-field,从一百万起算。
为什么要这些，慢慢给你算：
你要看碳管，至少要能看见缺陷吧，否则一般只是看厚度什么的有什么意义？这个现在
只有titan +cs correction才能有原子级别的解析度。
碳管/graphene，严格来说不是晶体，所以如果你要看单层graphene，一定要用High-
angle annular dark-field 才能看见原子排布，缺陷，位错什么的
碳材料又是很 beam sensitive的，所以平常200kvmode太强了，所以至少还要再配一个
20kv mode的
最后，如果你们想发science nature，至少还要搞insitu的成像，所以还要讨论一下要
不要加加热器，通气体…………然后最重要的还是要配备一个专业搞电镜的。
当然如果你们只想看看碳管直径，最多是数数有几层，所谓graphene至少有10层20层，
那么随便那家，越便宜越好。国产的据说都有了。 |

者、天文爱好者们尽可追随观赏。其中，最受瞩目的将是2019年1月21日的超级血狼月。
2019年将会有五个日食，一个罕见的水星凌日（Transit of Mercury），最好的流星雨
，以及备受关注的超级血狼月（super blood wolf moon）。
不止如此，在新的一年里，天宇中还将出现三次超级月亮，一个蓝月亮，多个流星雨，
木星合月景观，以及数次火箭发射活动。
以下是CNN网站整理出的2019年精彩缤纷的天文奇观。
1、1月6日：日偏食
美国宇航局（NASA）的消息，在2019年的第一周，月球将在地球和太阳之间穿过，天宇
会出现日偏食（partial solar eclipse）。
不过，只有东北亚的居民，以及北太平洋地区才可欣赏到这一天文现象。月偏食将在美
东时间1月6日晚上8:42左右发生。
Sky&Telescope预测，地处北京的人们将看到20%的太阳，在东京将看到30%的太阳，俄
罗斯海参崴的居民将看到37%的太阳。

During this month's annular eclipse, strategically placed observers — perhaps
on a ship crossing the Pacific Ocean — can use solar filters to view a
brilliant ring, or annulus, of sunlight as the Moon passes directly in front
of the Sun. (This won't be a total eclipse, because the Moon's angular size
