Hi Brad,

Thank you very much for your reply! Besides what Andreas has already
answered I’d like to ask if you know of any references where we could find
out more about SGP/SDP orbit determination models?

We’d also like to ask the community how we can organize this collective
call for observations. We are new to the community and have no experience
in how they do these things...

We read that it will be difficult for you to observe in the next few days
the objects we listed, so we will look for some alternatives and will give
them to you asap; and also if you have any suggestions we are happy to
consider them.

Thanks!!!

Best regards
Jorge
