Last night Comet ISON suddenly brightened and may be bright enough to be visible to the naked eye..  The comet is now within the orbit of Venus and falling with increasing velocity toward the sun for its November 28th perihelion.

Here’s a link to Universe Today‘s post with lots of photos.

EarthSky also has an entry for it: with a finder chart for naked eye viewing of the comet in twilight.

Here’s SpaceWeather.com‘s entry for today.

This may bode well for the comet’s brightness after perihelion, if the comet’s nucleus holds together or stays in big enough pieces.  The next week may tell.
