Plan: On descending leg just after apogee, radiation levels low.

doing OBSID 02241, QSO 1508+5714 2001:161:23:58, ACIS-S NONE, DIRECT
DETECTION OF COSMOLOGICAL DUST: an X-ray scattering halo.

then OBSID 02073, NGC 3607/NGC 3608 2001:163:01:26, ACIS-I NONE, IN
SEARCH OF ``NORMAL'' ELLIPTICAL GALAXIES: the X-ray properties of
``normal'' ellipticals to compare with those in rich clusters.

(2) SSR dump halted due to large changes in CFC count, indicating
    poor telemetry quality.  Restarted after some tweaking at DSS-54.
