    Lacrosse 4 (00047A / 26473) is very roughly consistent with the observation report:
    The first four Lacrosses had a distinct orange-red hue, due to the gold coloured thermal blanket that covered much of their surface.
    The satellite culminated at about 48 deg, a bit lower than the reported 60 deg, but it is common to over-estimate elevation above the horizon.
    The reported 10 s for it to disappear is typical of satellites entering eclipse, but the wording of the report seems to suggest this occurred at about 60 deg, which is way off.
