    Over the past few decades I have read about several comets that initially brightened rapidly while still 2 or 3 AU out, but fizzled when getting closer. Apparently they were first-timers and had surface volatiles but no vents from the interior to sustain the show once the superficial stuff was gone. An opposite case was Comet West of 1976, which became much brighter after breaking up near perihelion. The fragmentation apparently exposed volatiles and dust that otherwise would have stayed bottled up.

    Things don't look too good for the great comet Atlas.

    Comet Atlas is a great comet, at least as seen by the HST.

    A great comet in the same sense that Kohoutek was a "great" comet.
