[Bill Gray]

Hi folks,

    I've posted pseudo-MPECs for EMM (Hope) and its booster :

    and for the two Tianwen-1 objects :

    (All of them already in need of updating.  Except for
the EMM spacecraft,  which is down to about mag 23;  we've
gotten all the data on it that I expect to see.  I'll hold
off a bit;  more data may come in from observers in Europe
over the next few hours.)
