They haven't shown up yet in the thirty.tle file, so I'm not certain of
the proper names for each object.  I know from the ETS-7 website at
http://yyy.tksc.nasda.go.jp/Home/This/This-e/ets-7_e.html  that the
target altitude for the chase/target pair is 550km, so I'm guessing
that they are the B and C objects that were placed into a higher orbit.
The A object is probably TRMM, and the D object is likely the 2nd
stage booster.

Using an early elset for the A object, I was unable to see anything
using binos and a scope during a pass in strong twilight at 6:24 PST.
As a consolation, HST glinted to -2 for a few seconds while I waited for
TRMM to appear.  I admit to being distracted by that display, and may have
missed TRMM as a result.
