    	Yes I believe its standard magnitude is too bright.  I tried naked
    eye observations of it last summer and never saw it.  I reported such in
    the message http://www2.satellite.eu.org/seesat/Jun-1999/0077.html.  I
    haven't looked for it since then so I don't have an idea of how bright it
    really is, though I suppose if it's the same kind of rocket as the others
    (#19468 and #20791) its standard mag should be around 6 (not 3.5).
