彗星快讯-SWAN

Dear All,
I received a message yesterday from Rob Matson that he's found a new comet in the
SOHO/SWAN data, and it seems that at least a couple of other astronomers have taken
confirmation images of it. I suspect it will be announced at some point today.
Rob mentioned that there's the possibility of it being visible in LASCO C3, perhaps as
soon as this weekend. Of course, it's very uncertain as we don't have an orbit for it and
we don't know if it will be bright enough. But please consider this a heads-up that if a
non-group comet turns up in C3 in the next few days, it could be this one.
I'll give you more information once I know it.
Regards,
Karl

星空下的Cwalker
美国人Rob Matson于世界时11月29日在SOHO SWAN图上发现一颗非族彗星，亮度11等左右，随后均被E27和E12拍到。@CNSOHO 苏华早在11月17日就注意到了此目标，但当时误将该目标认为是C/2011 R1而错失发现。至于该彗星能否出现在LASCO C3图上还是个未知数，因为目前还没有精确的轨道，无法得知它未来的亮度。

SWAN上的彗星 11月10日的图片可以清楚看到2011L4和2011R1，预报2011R1今年10月过近日点，亮度预报12.1等，但是SWAN上显示大大亮于预报，是爆发吗？看了MPEC没有地面的观测。

仔细整理了一下目前已经得到的资料。
美国人Rob Matson于世界时11月29日在SOHO SWAN图上发现一颗非族彗星，彗星亮度11等左右，随后均被E27和E12在地面上拍到。我国天文爱好者苏华早在11月17日就在SWAN图上注意到了此目标，但当时误将该目标认为是C/2011 R1而错失发现。至于该彗星能否出现在SOHO LASCO C3图上还是个未知数，因为目前还没有精确的轨道，故无法得知它未来的亮度。

我发现我犯了个严重的错误：
彗星应该这么飞的
就因为疏忽，把SWAN上的270度黄经看成了225度（每根线代表45度），这样推导出是R1，其实目标并不在那个地方，而是在黄经280度附近，这里根本没有已知彗星，坐标系看错位了，完全可当新彗星上报。

Ogura found the observations were best represented by an elliptical

Ogura 的观点这是一个椭圆轨道，他计算显示周期可能为46和63.8年，后者可能性更大。
D/1827 M1 (Pons-Gambart)
Discovery This comet was discovered by Jean Louis Pons (Florence, Italy) and Adolphe Gambart (Marseilles, France) on 1827 June 21. Although no system was in place to estimate comet brightnesses at that time, various astronomers have since suggested the comet was then between magnitude 5 and 6.
发现
这个彗星在1827年6月21日由意大利马赛的Jean Louis Pons 和法国的Adolphe Gambart 发现，虽然那时没有系统的测量亮度，但是一些专家估计亮度在5到6等之间。
Historical HighlightsFew physical descriptions were published for this comet. Pons was the most prolific observer, measuring three additional positions in June and a total of 17 in July. The comet attained its most northerly declination of +83° on June 26. J. E. B. Valz (Nîmes, France) saw the comet on the morning of July 5 and 6, and on the evening of July 6, with a nearly full moon in the sky. The comet attained its maximum observed elongation of 63° on July 7. The comet was last detected on July 21 by Pons. He said the comet was extremely faint. Pons added that the comet could not be observed thereafter because of its faintness and the fact that it had entered a region of the sky containing numerous nebulosities.
历史集锦
一些公布的信息描述了这颗彗星，Pons有很详细的观察，测量了6月3个和 7月17个位置，彗星6月26日到达赤纬最北端+ 83°，法国Nîmes的J. E. B. Valz 在7月5日和6日早上和7月6日晚上看到这颗彗星，7月6日晚几乎是满月。彗星7月7日到达63度的最大角距。Pons7月21日最后观测到这颗彗星，他说彗星非常暗弱，之后无法观测是因为彗星很模糊，并且进入了包含很多星云的天区。
A month of observations did not generate great interest in examining the orbit of this comet. It was not until 1828 that the first parabolic orbits appeared in the Astronomische Nachrichten. During March, Valz took positions spanning the entire period of visibility and determined the perihelion date as 1827 June 8.83. One month later, A. de Heiligenstein essentially used the same positions and determined a perihelion date of June 8.37. There was no further interest until the 20th century, when, during 1917, S. Ogura took 74 positions spanning the period of visibility, and found the orbit was distinctly elliptical. His best orbit had a perihelion date of June 7.69 and a period of 63.83 years, with a likely uncertainty in the period of +/-10 years. A second orbit with a period of 46.0 years was calculated, but it did not fit the positions as well. S. Nakano reinvestigated the orbit in 1978. He said the 1827 observations were best represented by an orbit with a perihelion date of June 7.64 and a period of 57.46 years, but suggested a probable error of +/-10 years. The comet was considered hopelessly lost. In 1979, I. Hasegawa introduced an interesting twist to the investigation of this orbit. He pointed out that S. Kanda had noted in 1972 that there was a "probable" link between comet Pons-Gambart and a comet seen in 1110. Hasegawa began examining the observations published in ancient Chinese and Korean texts and was able to derive three rough positions, with which he then calculated a parabolic orbit. He confirmed the resemblance to comet Pons-Gambart. Orbital calculations revealed the comet passed closest to the sun on June 8, 1827. Following the discovery it steadily faded. The comet was seen for the final time on July 21 by Pons. Astronomers have suggested the comet was probably then near magnitude 8. Orbital calculations were strictly parabolic in nature until 1917, when Ogura found the observations were best represented by an elliptical orbit. His own calculations revealed orbital periods of 46.0 and 63.8 years, with the latter being considered more likely.
一个月的观测资料对研究这颗彗星的轨道并没有产生很大的关注，直到1828年天文学会新闻才有一个抛物线轨道。3月期间，Valz获得整个可见期的位置，并确定近日点在1827年6月8.83，一个月后，A. de Heiligenstein适应类似的位置数据确定近日点在1827年6月8.37，直到二十世纪前没有更多的关注。1919年期间，S. Ogura搜集了可见期间74个位置数据，发现了冥想的椭圆形轨道。他的改进轨道显示近日点在6月7.69，而且周期为63.83，周期的不确定性有+/-10年。计算的另外一个轨道为周期46年，但并不是很吻合观测数据。S. Nakano9（中野） 在1978年重新复查这个轨道，他说1827年观测资料最好的轨道是近日点是6月7.64，周期57.46年，但指出了坑能的误差+/-10年，估计这彗星已经丢失。1979年，I. Hasegawa（长谷川）发表了对它的轨道一个有趣的转折性研究，他指出S. Kanda1972年已经注意到Pons-Gambart a和1110年观测到的彗星之间的关联。Hasegawa（长谷川）开始研究中国和韩国古代的观测记录文献并从中得到三个粗略位置，然后计算了一个抛物线轨道，他确定和Pons-Gambart彗星的相似，轨道计算显示彗星近日点在1827年6月8日，随后发现它之间暗淡。 Pons最后在7月21日看到这颗彗星，天文学家认为彗星大概接近8等。直到1917年轨道都是按抛物线计算的，Ogura发布找到最吻合观测资料的椭圆轨道观点，他的计算表明，轨道周期为46和63.8年，但后者被认为是最有可能的。
I may add that the only uncertainty is the period. The initial period was in the
range of 46 to 64 years. So currently it is not clear how many perihelion
passages
we might have missed since 1827.

great news that this comet is finally back!
The period was given with 65.5 by Hasegawa & Nakano.
With the return now it would be around 62 years an we would have missed two
returns?

占楼 流星雨
这一个不引人注意的流星群是加里·克罗(Gary Kronk)在检查泽内·瑟卡尼纳(Zdenek Sekanina)在20世纪60年代所观测到的39145颗无线电流星时发现的，8月2-27日一共出现了6颗群内，极大出现在8月12日，辐射点位于赤经49.6度，赤纬-4.9度。其母彗星应该是周期彗星庞斯-加姆巴特(1827 II Pons-Gambart)，轨道很相似，但是近日距有差不多0.2AU的差异，轨道半长径的差异有3.5倍左右。
有意思的是，虽然没有关于这群直接联系的目视数据，但美利坚流星协会却在其北部8-10度的地方观测到较强的活动。阿登(Dr.H.L.Alden)和麦克因特什(Ronald A.McIntosh)分别在1926年和1929年观测到活动，类似的还有因斯蒂图德(Franklin Institute)在1941年，沃里(Charles E.Worley)在1954年以及梅兹格(Eli Metzger)在1958年。卡侬·霍夫梅斯特(Cuno Hoffmeister)在1948年出版的《流星夜话》中列出了5406个辐射点，说他1937年在西南非洲也观测到类似的流星群。
从上能得出的是，八月波江座流星雨非常古老，因此无线电群和目视群可能已经分成了两块。
庞斯-加姆巴特彗星仅仅被观测了一个月，人们认为其周期是57.5年，但后来再也没发现过。1979年有人计算了一颗在1110年出现的彗星的轨道，并发现这可能就是庞斯-加姆巴特彗星的上一次回归，看来其周期可能是1000年左右。 H47（美国）拍摄的SWAN12B
