Comet Jacques (C/2014_E2), brightest of the year (so far...)

Bright, spectacular comets are quite rare, while faint, little fuzzies are rather common. The current comet Jacques is just intermediate, barely visible to the naked eye, but offering a definitely nice view at the eyepiece. It was discovered by the brasilian astronomers Cristovao Jacques, E. Pimentel, y J. Barros from the Sonear observatory.

On the picture below we can distinguish the bright compact nucleus embedded in a dense coma that appears spherical, except for a subtle opening on the top, corresponding to the eastward very faint tail, almost reaching the upper edge of the field.
Note also the greenish colour that traces the presence of diatomic carbon (C2), an element commonly found in such comets.

Jacques is currently brightening, moving thorough Canis Major and heading to the Cone Nebula, that it will encounter on the evening of next May 29th...

Furthermore, comet Jacques is expected to brighten considerably by July and August : it could then become a naked-eye object, well visible from the Northern hemisphere, so just keep watching!...
