Hi Ron/List,

Given the length of the current arc (270 days), and the consistency of
photometry over that time, I will go out on a limb and say that this
almost certainly become the brightest comet that has ever been seen --
a significant margin -- by most people alive today.

What's particularly amazing is how close this comet will come to Mars
around October 1st next year -- less than 7 million miles! Hopefully
NASA/JPL will have plans in the works to schedule instrument pointing
and imaging of the comet using the suite of sensors both on and in orbit
around the Red Planet. For Mars, this will be a northern hemisphere
comet -- certainly visible from both rovers. --Rob

Comet ISON into a bright naked-eye object in Nov.
2013. First images and speculation about the comet are highlighted on
