New information on the identity of BRICSat, NO-83 has been been received
from Nico Janssen, PA0DLO.
Nico (with the help of Jan, PEOSAT) came up with an ingenious way of making
the tight-lipped BRICSat tell us which object it really is. See excerpt from
Nico's email to me below.

Therefore, the AMSAT distribution will begin using the ULTRASAT-2 TLEs for
Thanks to Nico, PA0DLO and Jan, PEOSAT for a really great bit of detective
