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.

Although it was predicted to be extremely faint as 26 mag, it unusually brightened up to 17.5 mag in outburst in 2013 July (July 6, Hidetaka Sato). However, no observations have been reported since mid July. It will pass the perihelion in 2014 August, and will approach to the sun down to 0.96 a.u. The brightness is predicted to be 23 mag at best. However, if the cometary activity continues, it may be observed brighter. Yasukazu Ikari reported it was not detected, fainter than 15.5 mag, on May 23. Date(TT) R.A. (2000) Decl.
