Ed Cannon sent me this URL:

http://www.spaceandtech.com/spacedata/logs/2002/2002-003_dash_sumpub.shtml

It says that DASH was supposed to separate from its adapter.

He also sent me:

http://spaceflightnow.com/h2a/f2/status.html

and this URL has the following:

>T+plus 41 minutes. Confirmation has been received that the dual
>payload adapter and lower two pieces of the rocket's payload fairing
>have been jettisoned as scheduled. That exposes the MDS-1
>satellite, which is set for deployment momentarily. But there still isn't
>clear confirmation of DASH being released.

So there may be two "pieces of the rocket's payload fairing"
up there as well.  The May SSR says:

                                     RCS
27367 02-003A  MDS 1                15.0
27368 02-003B  DASH                 1.25
27369 02-003C  VEP 3/H-2A           18.0

If they really have detected DASH with an RCS of 1.25 square meters
(which is correct for its size), then both its adapter and the two
fairings have not been cataloged.  All three of these objects should
be pretty big.  The DASH adapter seems to be hexagonal, so it might
give flashes from its flat sides.

An original elset for the MDS 1 payload was at 2.265, but it was changed
a few days later to 2.268:

Current elsets:

The unid was 2 degrees from A last night and should be only 1 degree
tonight and virtually the same place tomorrow night.  (if my mean motion
is correct)  The difference in mean motion (if correct) has meant that
the A object has completed one more revolution since launch than the
90012 unid.

The Hai Yang 1 payload has entered a stable orbit and appears to be
about 6th magnitude on a favorable pass:

1 27430U 02024A   02154.19415593  .00000576  00000-0  24363-3 0   386
