Alan, I have just checked both Celestrak and Space-Track and they are both showing Object 31132 as CP4. That's not to say the elements have not been assigned correctly to their respective objects. Recent work with Cute1.7 + APDII and IO-26 suggests you have to be careful at times, as objects do get "swapped" from time to time. There were a swag of Cubesats on that launch. Colin VK5HI.

In trying to copy CP4, I noticed that there is a discrepancy in the Keps being distributed. Jason's Keps give the object number as 31132. You get this from Space-Track, and it seems to give a good agreement. However, the Celestrak and those distributed by AMSAT give the object number as 31122. Close, but off enough that it makes automatic tracking nearly impossible. So when you do an automatic update of your Keps, be certain to go back in and put in the correct object.
