The comet Ison

Par BRUNO BOYERPublié le 21 nov. 2013 à 11:43

Comet ISON is called C/2012 S1 because it was discovered last year.

It's on track to swing very close around the Sun — missing it by less than one solar diameter! — on November 28th and then re-emerge into dawn view, possibly with a long tail, in early December.

As of November 20th it's about 4th magnitude, low in the pre-dawn sky and easily visible in binoculars if you know where to look. The much-reported naked-eye detections have required excellent dark skies as well as sky-map skills.

How visible will it finally become ?
