Those interested in STMSat-1 should look at the following website for TLEs. http://www.stmsat-1.org/
See AMSAT-BB for the latest news and a running commentary. As of the date/time of this email, Space-Track has not yet posted TLEs. As Bob KO6TZ has pointed out on AMSAT-BB, the TLEs for the ISS are also a good short term starting point.
Also AMSAT-UK has more info on all the cubesats launched today and their frequencies/modes at the following website. https://amsat-uk.org/
