The comet is on its way out of the inner solar system, having made perihelion last spring. The gas cloud has expanded to 70% of the diameter of the sun.

I did appreciate the coverage by Phil Plait. I had a hard time seeing it because of the light pollution here in Minneapolis/St. Paul and the full moon. I did appreciate the coverage by Phil Plait.

We started to get a naked-eye view of Comet 17P/Holmes last week…

I'd totally forgotten to go out and look for it, as it was overcast all last week, but I'll be sure to get my giant binoculars out tonight. Nice photography!

Therefore its tail will be flowing away from us explaining why we only see a 'fuzz-ball'. The tail is just beginning to show now see: " Comet Holmes Grows a Tail "http://antwrp.gsfc.nasa.gov/apod/ap071105.html. The interesting thing about the comet is the gas cloud was ejected, spherically while the comet was going away from the Sun, therefore some underground cavern that had been sublimating on the approach to perihelion must have given way but only after maximum heating stress.
