* C/2014 E2 ( Jacques )

Now it is so bright as 7.9 mag (May 24, Chris Wyatt). It will approach to the sun down to 0.66 a.u. in July, and it is expected to brighten up to 4-5 mag. It is already not observable in the Northern Hemisphere. It will be unobservable in early June also in the Southern Hemisphere. 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.
