With just one month to go before its dramatic solar rendezvous, skirting to within a hairbreadth of the surface of the sun, Comet ISON continues to befuddle observers with its performance en route to the sun.

Looking weird

The highly regarded comet observer John Bortle is just as perplexed by the comet's recent appearance, commenting that the recent images along with his own visual impression, is "downright weird." He adds that, "There is a bright, miniature, long-tailed comet situated within a much larger, but very much fainter and diffuse halo of a coma."

Bortle has observed several hundred comets and yet, he writes, "At this stage of the game, with the comet about to cross the orbit of Earth, I cannot recall any previous comet in my 50-plus years of comet observing looking quite like this. So, what does ISON's current look foretell, or mean? I honestly don't know. All I can say is I don't like the odd look of it at this time."
