    I had received your correction, but you did not address my concern. You reported
    the sign as positive, but to have been the object in question, it needed to be
    negative. It's a minor issue because to have been low your southeast, it had to
    be negative. Its just that I like to tie up any possible loose ends.

    My revised elset puts the elevation during the burn at 11 deg. Of course,
    elevation can be difficult to judge, and most folks tend to over estimate it.
    The elset still is rather rough, so further tracking might change the elevation
    estimate a bit.

    Made mine too! I had been so wrapped-up in the ascent trajectory and propellant
    dump, that I did not think to check whether or not anyone was in a position to
    see MES2. I am so glad that you were thinking - and willing to try to observe
    such a low elevation pass.
