日食照片
  2009年7月22日上午发生了一次日全食日全食带从西向东的扫过以下主要城市。居在这些地区的人可能看到了百年难得一遇的超长时间日全食,全食时间长达4-5分钟,对于日全食来说,这是一个漫长的黑夜了。
   康定、雅安、乐山、成都、自贡、内江、遂宁、南充、重庆、达州、黔江、宜昌、荆门、荆州、江陵、沙市、考感、咸宁、武汉、黄冈、鄂州、黄石、六安、合肥、安庆、池州、巢湖、芜湖、铜陵、黄山、宣州、马鞍山、湖州、常州、无锡、苏州、杭州、嘉兴、绍兴、上海、宁波、舟山。这几乎是整个长江流域都能看到日全食了,大约将会有四亿人看到。7月22日日食带天气并不理想,导致上海等地没有观测到日全食。

观测提示编辑本段回目录

观测点的选择
目前各大媒体争相报道所谓的最佳观测点,并不全可信,因此在观测点的选择上,不必过度听信媒体炒作,对于长江中下游正处于全食带内的观测者而言,只需在自己城市内寻求较好的观测点即可。
需要注意的事项有:1、观测点的交通是否便利:一旦出现了云遮,需要一个较好的交通来进行转移
2、楼房遮挡情况:需要确保观测时太阳没有被楼房等障碍物遮挡
3、选择地点最好具有代表性
拍摄的方法
在拍摄日全食的时候,如果有较好的器材,可以选用数码单反相机拍摄,在偏食阶段一定要盖上巴德膜!对于没有此类器材的观测者,可以采用摄像机对日食场面进行摄像、录音等,留作纪念。
观测的方法
日全食的观测切不可直接使用肉眼。如果需要目视观测,可采用专门的日全食观测眼镜,价格大约为3-5元(一般而言厂商的批发价格约为3元),这种眼镜是有纸和巴德膜制成,没有金属镜框。如果采用望远镜观测,需要使用巴德膜,不可直接将望远镜对准太阳,然后将眼睛对准目镜观测,这将导致失明。如果没有巴德膜或者不方便购买,可以将望远镜的目镜取下,然后将太阳像映射于地面观测,也可以利用小孔成像原理观测。
警告:由于此次日全食影响广大,很多媒体都刊登了所谓的安全观测方法,但其中有的并不安全
1、不可以用墨镜观测,或者在眼镜上涂墨水,墨镜的虑光效果不够,会损伤眼睛视力,不排除导致失明
2、有媒体传说可以用多层墨镜,或者用CD片观测,这类物品即使可以虑光使得眼睛不觉得光很强烈,但是他们不可以过滤非可见光,太阳发出的红外光可能灼伤你的眼底视网膜,导致失明
3、有的书籍媒体声称可以在水里滴几滴墨水,利用反射观测。注意水在盆里不是完全的平面镜,有可能有焦点,而且这种犯法并不能很好的观测,你仍然会感受到强烈刺击!就像某些玻璃楼房反射强光一样。
