Do you know when this will be visible from land? in australia
I know that the common theory of comets is that they are dirty snow balls but how could that be ?. They don't have the atmosphere or the geothermal mass to have anything like heat to melt and make them light up .If they have been running around our solar system for as long as they claim ,wouldn't they have vanished by now?

I think that the gravitational aspect fails in my mind . I mean like even our little satellites spinning around our earth need to be readjusted or they end up back down here .To think that a snow ball without rockets strapped to it have been making the rounds for millennia and not being sucked into our sun or planets just seems strange .

Any astrophysicists out there care to offer a reason why the brightness suddenly jumped?
Perihelion was back in mid-August.
According to the (prevailing) icy dirtball theory, the brightness should be well correlated with the distance from the sun.
A significant number of comets have light curves which have brightness anomalies vs. distance from the sun. Is there a classical explanation?
Cbet No. 3674, issued on 2013 October 21, reports an outburst in brightness of comet C/2012 X1 (LINEAR). The magnitude of the comet was measured by reported by H. Sato on on Oct. 20.5 to be total mag 8.5 (as measured within a circular aperture of diameter 85".2) with a brighter center about 10" across. The predicted H_10 magnitude for C/2012 X1 (LINEAR) would be around 14 now
