To show you how uncertain this whole thing is---this morning I went to Space-Track and got a set of keps for these birds. Most were dated with "day 304".
Just now, I went for another "fresh" set--they had gone back to "day 303" and when compared to the previous set from early this morning, and all the AOS times are about 2-3 minutes different!
Heh.

We suspect RAX-2 to be Object E. Our ground station rotators though are failing so we're having difficulty tracking. Our new Alfa Spids should arrive this week so we can fix.
The Utah team tracked objects B and D and they were able to communicate with their satellites. Since they are using high gain, narrow beam antenna, there is little doubt that these objects are antyhing else.

James Cutler "is" RAX-2...he's the faculty advisor to the students who built it.
The website is most certainly behind, because we are just now getting KEPS via SpaceTrack.
RAX-2 is probably one of the objects C, D, E, F, G listed below--but most likely NOT A, B, or H.
Here they are again--grabbed just now:

None of these are RAX-2. At least, not if the RAX-2 website is right. There are people tracking RAX-2, so would you please share the keps you are using?
Thanks,
