[原创翻译] SOHO彗星管理员对寻慧新手的建议

Dear Yan,
严先生，

Yes, this is the correct email address to use. All the SOHO comet reports should be reported at http://ares.nrl.navy.mil/sungrazer
是的，这个电子邮件是正确的。所有的SOHO彗星报告都应该被发送到 http://ares.nrl.navy.mil/sungrazer。

I have looked at your reports below, and they are not comets. The comets we see in the LASCO C3 images move *much* more slowly than the positions you give, and they move in an almost perfect straight line. It is very rare to see a curve on the comets' path.

我已经审查了你提供的报告，但是他们都不是彗星。我们能够在 LASCO C3 图像中看到的彗星移动的速度比起所给出的报告显然是慢得多的，而且它们都是近乎直线的在运动。弧型的彗星轨迹是非常罕见的。

When we get newcomers such as yourself, I always offer some standard advice to help. First, If you haven't done so already, I strongly recommend you read Sebastain Hoenig's tutorial (see "Other Links" page) on SOHO comet hunting. To familiarize yourself with the size and motion of SOHO comets you should look at the "hoto Gallery" page. A common mistake is that people assume a comet will be bright and have a tail. This is *very* rarely the case. The vast majority of our comets are small star-like objects, often only 2 or 3 pixels wide, that move only a few pixels per hour. In fact we get many people mistaking stars for comets -- it's worth remembering that stars move horizontally in the LASCO field of view -- comet DO NOT! Out of the 763 comets we have, I have only seen one that moved almost horizontally. Most SOHO comets belong to the Kreutz group. These comets always appear in the lower part of the images and move towards the Sun. Their approach angle varies a bit throughout the year (see http://www.ph.u-net.com/comets/c2paths.htm).

当我们遇到像你这样的新手的时候，我们都会提供一些常见的建议。首先，如果您以往没有进行过在 LASCO 中搜索彗星的工作，我强烈建议你阅读在SOHO彗星搜索的 Sebastain Hoenig's tutorial （"其他链接"页面中）。为了让你熟悉SOHO彗星的尺寸和移动规律，我觉得您应该看看"图片库"。通过情况下，人们往往对SOHO彗星有一个误解，他们认为彗星应该是明亮的、并且具有慧尾，但是在SOHO彗星的搜寻中，这种情况是非常少见的。在我们已经发现的SOHO彗星中，绝大多数看起来都是和普通的星星一个模样，它们往往只有2-3像素宽，每小时的移动仅仅只有很少的像素。事实上我们收到的很多可疑彗星报告都是将普通的星星误认为是SOHO彗星。请记住：在 LASCO 的圆形视场中，星星是水平移动的，但是SOHO彗星都不是！在已经确认的763颗SOHO彗星中，我只见过一颗以近乎于水平移动的彗星。大部分的SOHO彗星都是 Kreutz 族。这些彗星总是在图像的下面部分出现，并且向着太阳移动。在一年中，它们的角度变化并不大（http://www.ph.u-net.com/comets/c2paths.htm）。

I will add your name to the list of comet hunters on the "Found Something" page. I recommend you look at other people's reports to see the way they do it, and also read the instruction page:
http://ares.nrl.navy.mil/sungrazer/instruct.html

我将把您的名字添加到"彗星猎手"的列表中，我建议你看看其他"猎手"的报告以及我们的指导教材（http://ares.nrl.navy.mil/sungraz ... �些什么东西。

Please feel free to email me with any questions. You can use sungrazer@nrl.navy.mil or karl.battams@nrl.navy.mil -- either is fine.

如果有什么问题，请不要犹豫来联系我，你可以使用 sungrazer@nrl.navy.mil 或者 karl.battams@nrl.navy.mil，两个都行。

Best Regards,
~~Karl
