C/2014 E2快速增亮（3月30日更新，彗星超出预期）
本帖最后由 suhuasky 于 2014-3-29 12:51 编辑今晚月出之前我目视观测了C/2014 E2 Jacques（雅克）彗星。2014月19.41 UT：M1=10.7，直径=3'，DC =4...20厘米反射镜，67X...Michael（维多利亚Swan Hill）
[[Tycho 2 VT比较星。彗发轻度到中度浓缩，并用Swan 带通滤波器略有增强。
这个位置的绝对亮度大约7.5，假设n = 4时得出峰值亮度大约6.5等。
Michael Mattiazzo
附：根据最初的光度数据的预报为14.2等，这个观测报告比预报亮3.5等。

C/2014 E2 Jacques（雅克）， SONEAR 在巴西捕获，这张照片由rolando ligustri3月21日拍摄，DK500/2250 CCD PL9000，彗发喷发大量的气体，非常活跃，乐观的估计最大亮度可到6.5等。
好期待啊。。。。。。。。。。。。。。。 3月21日拍摄，azeq6+250f5牛反+qhy9，测光孔径2个像素，亮度为14.4左右。小家伙跑得很快！！ 视星等还是偏高，比较暗。 本帖最后由 suhuasky 于 2014-3-29 12:52 编辑
COBS根据目前为止的观测数据给出的光变曲线和模型，碉堡了，如果照现在的势头发展，彗星如果不出现瓦解，亮度极大有可能达到0-1等。当然，彗星是最具戏剧性的天体，所以谨慎乐观以观后效。

我勉强拍下的2014E2：
C/2014 E2 Jacques，2014年3月27日拍摄，低空，严重光害，90/500+EQ3-2+SONY a550,30SX41 dss+1暗场叠加，裁剪边缘，Pleiades PixInsight LE 1.0人工平场，PS+光影魔术手。
使用Comet for Windows录入从各个渠道获得的C/2014E2观测数据，得到的拟合光变曲线和COBS的一致，不过因为观测时段短，从发现到现在不到半个月，因此不能排除是一次爆发过程，就像C/2012 X1，所以还需要继续跟踪彗星的变化。另外，SOHO卫星的SWAN在24、25日的照片上已经能够清晰地看到C/2014E2。
变数太大，给人惊喜的少之又少。 本帖最后由 suhuasky 于 2014-3-30 12:54 编辑
从发现到现在还只有半个月,还不能给出最终预期,发现时是14-15等(CCD测光），目前的目视星等在10等多，因为早期亮度数据是CCD星等，CCD星等本来就和目视星等有差异，如果用CCD星等和目视星等参杂推算会出错，所以使用传统标准光变公式 m1 = 8.0 + 5 log d + 10.0 log r，那么最大亮度大约在6-7等。
未来几个月是值得关注的，而且位置很好可以持续监测变化。
希望有惊喜 Nirmal Paul 3月30日通过澳大利亚赛丁泉天文台T9 0.32-m f/9.3Ritchey-Chretien 望远镜+CCD+减焦60秒曝光 bin x 2 拍摄的彗星C/2014 E2（雅克），我估测了下亮度。

下调C/2014 E2峰值亮度预期。
经过几天的目视观测数据，光变拟合曲线显示极大亮度约5等上下，光变公式：6.49+5log d+14.81log r
