How big will it get???

Every single day the halo around the comet is bigger. The leeward side continues to get increasingly diffuse while the opposite side is still pretty well defined as the shell expands. Are there any projections? I'm down to my 32mm 2" Koenig and it's still getting mighty big in the window. 8O

According to the veteran observer and writer Tom Polakis, the main coma (not the faint outer halo) has been expanding at a constant velocity of 575 meters/sec since the time of the initial outburst on October 24. This means that by Saturday, November 3, it will be 15 arc minutes in diameter and a week later an incredible 25 arc minutes. These figures correspond to physical diameters of 1,065,930 and 1,776,551 kilometers.

The faint outer halo, of course, is much larger.
