Hi Daryl,

    We have some observations now...

    ...from which we can say something about what brightness to expect :

    I've gotten some confirming observations at a similar magnitude.

    Your friend might be able to get both JWST and its booster, 
somewhere around mag 13 when night falls on the east coast of the US at 
0:00 UTC tonight and dropping about a magnitude over the next twelve hours.

    And if your friend happens to measure astrometry from the images, 
especially of the booster or of any other hardware that shows up,  I'd 
be quite interested.  (JWST will be tracked to a fare-thee-well,  I'm 
sure,  using radio.  The booster and any other bits of hardware will be 
mostly ignored,  though they'll be a minor annoyance for the asteroid 
surveys.  I'd like to be able to tell them where such stuff is going.)
