This is probably an underestimate. By the time this is posted,
the angular width of the coma will be on the order of 15 arc
minutes or larger. The current range from earth is roughly 2.4 x
10^8 km. The implied diameter of the coma is thus just over 10^6
km, or about 150 times the size of Mars.

This is not the first time this comet has undergone sudden
outbursts. See:


I observed this comet last night with a small reflector under
excellent seeing conditions in western Colorado. It is quite
striking, and evolving substantially on a daily basis.
