Koichi Nishiyama, Kurume, Japan; and Fujio Kabashima, Miyaki, Japan,
report their discovery of a possible nova (mag 17.3) in M31 on seven 40-s
unfiltered CCD frames (limiting magnitude 19.8) taken around Sept. 30.566 UT
using a Meade 200R 0.40-m f/9.8 reflector (+ SBIG STL1001E camera), as
tabulated below. An independent discovery has been reported by Guoyou Sun
(Wenzhou, Zhejiang, China) and Xing Gao (Urumqi, Xinjiang, China)
on 60-s unfiltered CCD survey images (limiting mag about 19) taken by Gao
in the course of the Xingming Observation Sky Survey at Mt. Nanshan around
Sept. 30.678 using a 35-cm Celestron C14 Schmidt-Cassegrain telescope at
f/7.5 (the measurements tabulated below are by Sun), adding that nothing is
visible at the same position on images taken on Sept. 9, 10, 11, 15, and 29
(no limiting magnitude given).T. Yusa, Osaki, Japan, also reports his
confirmation of M31N 2010-09b on unfiltered CCD frames (limiting mag 18.2)
taken on Oct. 1.42, following a request from Kabashima and Nishiyama, using
a 0.30-m f/9.9 Cassegrain telescope (+ SBIG STL-1001E camera), with his
data also tabulated below; he has posted his image at the following website
URL:http://space.geocities.jp/yusastar77/PNinM31_101001.htm.
Wolfgang Pietsch, Max-Planck-Institut fuer Extraterrestrische Physik,
reports a pre-discovery observation from CCD images obtained with the
robotic 60-cm telescope of the Livermore Optical Transient Imaging System
(cf. CBET 2124), also tabulated below.

Nishiyama notes that M31N 2010-09b is located 690" east and 494" south of the
center of the galaxy M31.Additional magnitudes for M31N 2010-09b:1986 Nov.

很可惜，又比小日本慢了点，不过这是我们第一次上报m31新星，能有个独立发现，还算不错，也算开天辟地第一次，这也代表这国内爱好者正式进入，系外新星搜索行列。
相信我们早晚会成功。革命尚未成功，我们还需努力！ lz是星明天文台的？ 恩，这个独立发现，有我一份。 没图啊
想看看图呢 http://space.geocities.jp/yusastar77/PNinM31_101001.htm

每天都让小日本抢先，下次一定要比小日本快 恭喜 恭喜啊 非常恭喜，呵呵。 本帖最后由 0003f 于 2010-10-2 12:17 编辑
升级设备，入一台24寸R-C，下次干掉小日本::42::。 每天都让小日本抢先，下次一定要比小日本快

我觉得不是偶然的，日本比我们天黑的早啊 ls，说的很对。 对啊，池谷-张彗星的发现不就是因为咱们天黑晚吗 小日本的地理位置太优越了，东边是太平洋，没人跟他争。 不仅仅是地理位置的原因，更重要的是日本从事新星、超新星搜索（在其他观测项目上也是，如变星、掩星等）的人有很多，这就增加了首先发现的概率，这才是我们始终落后于人家的重要原因。国内从事这些有意义观测项目的人有多少呢？ 观星，需要政策扶持::070821_18.jpg:: LZ是孙国佑吧，恭喜恭喜！
独立发现这有所有权和命名权啊，呵呵 独立发现貌似没有发现权，我也不是很了解。命名权肯定没有，新星都是没有命名权的。只有小行星，彗星有命名权。 没在群里祝贺你，在这里更好！
刚开始我还真以为是一个一般的变星呢。
孙祝贺你呀！ ::070821_19.jpg::
