Remember how I mentioned that the "tails" on those cometary knots are around 100 billion miles long? To put it in proportion, that's over 10 times the diameter of planet Pluto's orbit, but still only 1/60th of a light-year, or about a light-week. Thus, if there are changes in the lighting of a certain knot, it takes about a week to become apparent.
