C/2014 E2 ( Jacques )
It brightened up to 7.0 mag until early June (June 9, Michael Mattiazzo). It had been brightening very rapidly, but the brightness evolution slow down recently. Michael Mattiazzo reported it was 7.5 mag on June 21 in SOHO images. It will approach to the sun down to 0.66 a.u. in July, and brighten up to 6 mag. Now it is not observable. After the perihelion passage, it will be observable in excellent condition after late July in the Northern Hemisphere. In the Southern Hemisphere, it keeps unobservable until early September.

C/2014 E2 Jacques（雅克）
直到六月初它的亮度增加到7.0等，（6月9日，Michael Mattiazzo）。它的亮度一直增加得很快，但最近亮度变化减缓。Michael Mattiazzo报道6月21日在SOHO的图像是7.5 等。它将在7月从0.66AU接近太阳，并到达6等。现在无法观测。近日点通过后，北半球将在七月下旬后观测条件变好。南半球直到九月初无法观测。
