    Water dumps are visible to the unaided eye; here is some information and photos:
    
    http://www.satobs.org/h2o_dump.html
    
    
    Fuel dumps and even orbit manoeuvre burns have also been observed with the
    unaided eye. Here are some reports I found by searching SeeSat-L's archive:
    
    Tony Beresford observed the Centaur propellant dump of the Titan 4 that launched
    Cassini on 1997 Oct 15 UTC:

    Ed Cannon and Mike McCants observed the Centaur fuel dump of the Titan 4 launch
    of 1997 Nov 8 UTC:

    Ed Light observed the fuel depletion burn and subsequent venting of the Delta 2
    launch of 1998 Apr 28 UTC:

    Ron Lee observed the fuel depletion burn and subsequent venting of the Delta 2
    launch of 1999 Jul 10 UTC:

    Ron Lee observed the fuel depletion burn and subsequent venting of the Delta 2
    launch of 1999 Jul 25 UTC:

    Dan Deak observed the fuel depletion burn and subsequent venting of the Delta 2
    launch of 2000 Feb 8 UTC:
    
    http://satobs.org/seesat/Feb-2000/0171.html
    
    
    The Centaur fuel dump of the Titan 4 launch of 2002 Jan 16 UTC resulted in
    several detailed observation reports, and a video:

    The fuel dump of the Ariane 4 that launched Spot 5 was observed from North
    America; we received several detailed reports:

    The Centaur of the Atlas 2AS launch of 2004 Aug 31 UTC put on a spectacular
    show, several thousand kilometres over eastern North America, as reported by
    several SeeSat-L subscribers:

    The final Centaur burn of the Atlas 3B launch of 2005 Feb 03 UTC was observed to
    reach at least mag 2, by Robert Holdsworth:
    
    http://satobs.org/seesat/Feb-2005/0022.html
    
    A short time later, Dan Deak had a spectacular view of the Centaur's propellant
    dump. He provided a detailed report, followed by a message with links to
    excellent drawings:
