7Timer! Seeing function available after 11hUT, June 25

Hello all,

  After seven days' working, today the seeing function is available. I have nothing more to say but enjoy, everyone!

  Together available functions include "Low Cloud Cover", "Mid Cloud Cover" and "High Cloud Cover", and a newly write running commands (which will reduce 90% command file size!). Hope you all like it!

Regards,

Quanzhi

“今天的报纸在哪里?”我问老妈。我其实想出去活动一下了。

“你下去拿吧。”

“好。”

我带上钥匙出门了。

夏至的广州,白天毕竟不如北方长,七点半就已经差不多天黑了,楼道里黑乎乎的。我忽然极自然地想起以前的一件事情。

高考前的某一天,不用晚修。我吃完饭,还是照例回到了学校。我觉得在学校晚修更好。

没什么人。楼梯灯都没开,黑黑地,颇为森然。我没想什么,探着黑暗上楼去了,拿了书本回到一楼的自修室自修。

许久。

第一场晚修结束了。我打算上楼,自修室离楼梯有一段距离,还要拐一个弯。我慢慢地走着,正想着森然的暗黑的楼道,抬起头,却见前面是隔壁班的一个女生—— 显然是住宿的,刚洗完的头发披散下来。她拐过弯,手轻巧地点了钮。楼道里顿时充满了灯光—— 虽然远不算光亮。

我跟随着她,一层一层地往上走,光明在我脚下延伸。到了三楼,我拐向自己的教室,却忍不住回头看上面的灯亮起来。

她在我心中成了一种圣像,虽然现在我还不知道她的名字,以后可能也不再有机会知道了。高中已经像曾经的黑暗,现在的光明一样伸展在我身后。黑暗经过她的脚下,就变成了光明,我们就靠着她和像她一样的人,才得以在光明下行走。

现在,我也是站在黑暗之中。自然地,我也轻巧的一按,头顶上那盏已经使用了至少12年的灯就又一次把光辉洒向楼梯间了。

我一层一层地往下走下去,它一层一层的亮起来。我走出铁门,打开信箱,把报纸夹在腋下,然后满意的欣赏我的杰作。

嗯,就象这样。我们前面总有黑暗,但总会有人站出来打开黑暗中的明灯,让我们得以继续前进。我们的心灵总有黑暗,但我们总能用爱燃起心灵的激情,继续歌唱着生命的乐章。这就是生活。

7Timer!-SP今日进展

基本搞定了,还有一些边角料。老外在这方面也真是挺刁的,我竟然一直没想到用他们的论文算出来的值还要加一点其它的参量,一直到看了欧洲气象中心预测的seeing图才发现seeing和涡度等有关系(汗,早就应该看出来了)。把相对涡度加进去,又加了几个二次系数,嘿嘿!出来居然和美国的GFS和CSC挺吻合的!Okay,我加了一些小改动,现在应该可以发表了。当然了,还有一点点收尾:

  • 在初步correct value上加以修改
  • 记得去掉test和check用的代码

似乎也没有了... 也应该睡觉了。

LUSSEC 21: CONFIRMATIONS ON C/2006 M2 (SPACEWATCH), 2006 KX38

CONFIRMATIONS ON C/2006 M2 (SPACEWATCH)

  On June 20.66, 2006, C. S. Lin and Q. Ye observed an NEOCP object SW40XA, which latter proved to be a new comet, which was discovered by R. S. McMillan of Spacewatch Project, U.S.A. The discovery was annouced in IAUC 8725 and the observations were published in MPEC 2006-M27. Here are the observations of Lulin Sky Survey:
    CK06M020  C2006 06 20.65718 16 02 05.22 +02 11 15.4          20.9 N EM027D35
    CK06M020  C2006 06 20.66800 16 02 04.62 +02 11 13.7          19.7 N EM027D35
  We did not reconized any cometary appearance of the object. The object is faint, star-like, a little bit diffuse on our image. The image of C/2006 M2, taken by C. S. Lin and proceed by Q. Ye, can be view here: http://csc.lamost.org/yeiht/wordpress/index.php?page_id=140&file=Lulin%20Sky%20Survey/sw40xas001r0011.PNG.
  On June 22, J. Young and R. S. McMillan respectively used Table Moutain's 0.6-m f/16 and Kitt Peak's 1.8m f/2.7 telescope, confirmed that the object has a 4"-6" coma. The object is now 4.6 AU away from the Earth, it has passed the perihelion on late 2005 at about 5.2 AU.

2006 KX38
 
  On June 15, H. C. Lin and Q. Ye failed to do a follow-up observations for a unusual LUSS object, 2006 KX38. As the orbit published in LUSSEC 20, 2006 KX38 was a unusual asteroid with e=0.45. It's possible that this object is a comet, as Q. Ye reported it was "diffuse" (LUSSEC 15). However, the failure on follow-up prove that the orbit was bad. We should go to re-check the previous observations. The orbit is based on a 4-day observations from May 22-26.

7Timer!-SP本日进展及一些废话

今天上午虽然惨不啦叽地写了一篇文章,但到底还是认真地干事,没有把时间花在这些无所谓的事情之上。但因为今天上午花了差不多一半的时间调查电站是否还能观星(过两天有可能和星会的人一同去观星),下午又和小迟去踢球了(太久不踢,没踢一小时就连续抽筋两次,还挂了外伤,只好回家了),回到家八点钟,又通过QQ给吉吉修电脑,到现在九点钟,可今晚还得制定鹿林巡天的计划,于是没有时间做SP了。哈哈!!……我真是充实。以前很担心自己考完高考,就成了失控的滑翔机,不知道自己的理想和目标了,可现在看来还没有多大问题呢。(闭嘴,成绩出来了以后再这么放4)

本周还有一大堆事情要做。首先,从小学到现在的好友YY(不方便随便公开名字了)邀请我去沙面听布道,但高考完之后时间并不如我想象的多,反而忙得连自己的事情都弄不完了(居然连锻炼身体都放了!不行,暑假我要天天游3km才行),结果一直都没去看个究竟。我先把现在看来,这段时间(这一两个星期吧)自己要做的事情列份清单,到时候好核对。

  • 7Timer!-Seeing Project
  • 7Timer! Extra (time up to 180h and try to reduce the resolution to 0.5 arcdeg)
  • Powerful version of LUSS Plan Master
  • Asteroid type determiner (用来对付自己那些小行星的,鉴于目前编程水平,可能不得不用GrADS下的fortran 90)
  • 关于TNO密度论文
  • 给天爱至少写一篇稿子 (也许可以用TNO密度论文顶一下? Note: TNO密度论文一定要在7月10日之前完成!)

好了,似乎暂时就这么多,够忙乎的了。废话少说,说一下今天的研究进展。今天的研究成果很少。

  • Fix了几个大bug (居然犯了单位出错的低级错误,该打!) 
  • 确认CN2求值过程无误
  • 主要怀疑:td温度差值不准确 (青藏高原上怎么会2米就差了18 K?按NODE171论文,2米温度差不会超过10e-03 K)
  • 初步认定(不是最终)epsilon求和过程无误,或者说应该也没问题
  • 一个想法:用south pole论文,以及程序生成的南极seeing值进行对照,修改程序内容 (现在的结果全是10e-02到10e-03的,郁闷!而且位置看来也不对)
  • 考虑在e_total加上海平面seeing的correction (高海拔地区的撇去)

似乎也不少了。ok!明天就要从这个地方开始做了。现在赶快去搞LUSS list吧,大忙人!

7Timer!-Seeing Project今日进展

今天8点钟就起来研究,到了现在又是12个小时了,汗…… 似乎进展不大。今日的进展有:

  • 昨天的目标都达到了
  • 100mb到850mb,以50mb为高度差进行了计算
  • 整体框架已经基本构建好,指令已基本写好

今天碰到的问题是:

  • 算的结果在域(12,34)之内,不符合预定标准
  • CT2值偏差了4个数量级

明天解决路线指引:

  • CT2->CN2转换应该问题不大,因为所差数量级(8-10个数量级)和NODE171论文偏差差不多。
  • 重点研究CT2为何偏差那么大的数量级,估计关键在此
  • 若检验之后,仍无法纠正CT2的数量级问题,解决办法有2:1.乘一个转换系数;2.把NODE171号文的sample做一个模型函数代入之。
  • 如果还是得不出正常结果,将Surface/2M差代入校正
  • 如果还得不出正常结果,到时再说

今天挫折也不少。下午休息时发现GFS放出了精度为55公里的数据,高兴坏了,可一弄才发现用的是GRIB2编码,而现在的GrADS 1.9根本不支持GRIB2,网上搜索了一下,办法是有的,但似乎太麻烦,没办法,只好不管了,去动力论坛发了一个询问贴。为了这个,浪费了1个小时左右。

[FW] Funny story of asteroid hunting

You know you are an amateur asteroid astrometrist when....

1) Your spouse checks MPECs to see where you were last night and who you were with.
2) You would like to see all stars not in the A 2.0 or UCAC removed from the sky.
3) Until you decide on a name, your newborn  baby gets a provisional designation.
4) If the police ask you, 'where were you on the night of.......' you check NEODys.
5) You refer to galaxies as 'the vermin of the skies'
6) You plan vacations and weddings to coincide with the full moon.
7) Your spouse wonders why you are so interested in One Night Stands.
8) When relatives send you family photos, you blink them to see if they've had any more kids.
9) At workshops you have no idea to whom you are talking until they mention their MPC code.
10) You check your bank statements for residuals
11) Your job is an annoying thing you have to do to finance your real work.
12) You love winter because the nights are long and the ecliptic high up.
13) You love august because the big surveys are rained out.
14) MPC issue day is the high point of your month
15) You ridicule your kids for playing computer games all day, then do exactly the same thing all night.
16) You spend 2 hours measuring the exact position of a 20th magnitude piece of noise before deciding not to send it in.
17) You dream of retirement so you can devote even more time to your hobby.
18) Asteroids II is your preferred bedside reading
19) You will happily relocate your entire family and change jobs for clearer skies.
20) You can find a small object at 400.000.000 miles but can't find your car keys.
