New Comet: C/2014 E2 (JACQUES)

Cbet nr. 3828, issued on 2014, March 14, announces the discovery of a comet (~ magnitude 14.7) on CCD images taken by  C. Jacques, E. Pimentel and J. Barros using a 0.45-m f/2.9 reflector at the SONEAR Observatory near Oliveira, Brazil. The new comet has been designated C/2014 E2 (JACQUES).

We performed follow-up measurements of this object, while it was still on the neocp. Stacking of 19 unfiltered exposures, 30-sec each, obtained remotely from MPC code Q62 (iTelescope, Siding Spring) on 2014, March 13.6 through a 0.50-m f/6.8 astrograph + CCD, shows that this object is a comet: very bright coma nearly 2 arcmin in diameter elongated in PA 10.

M.P.E.C. 2014-E84 assigns the following very preliminary parabolic orbital elements to comet C/2014 E2: T 2014 June 29.52; e= 1.0; Peri. = 349.10; q = 0.60;  Incl.= 157.19

Big Congrats to our friend Cristovao Jacques and all the SONEAR team for the discovery of their second comet! Click here to find more info about their first comet.

UPDATE - March 16, 2014

According to the very preliminary orbit, comet C/2014 E2 will have a close approach with planet Venus on 2014, July 13 at 0.088 AU.
