Has there been any serious attempt to take a photograph of the damaged
bird using ground based optical telescopes while it is in sunlight ?
With modern telescopes such as
or similiar and a modern digital camera and a known RA/DEC co-ordinate
of the satellite at any point in its orbit, it should be possible get
a fairly decent picture of what is still up there...
Note RA / DEC are astronomy co-ordinates which should be able to be
calculated from AZ/EL or TLE, but I may not be able to do it myself.
We don't need to track it, but just to image it in several consecutive
frames. From: http://www.emergentspace.com/pubs/AIAA_GNC_2002_AMSAT_A040.pdf
Table 1. Nominal Orbit Parameters for AO-40

Perigee Height (km) 1,042
Apogee Height (km) 58,691
Inclination (deg) 6.04
