TCP J21040470+4631129  (UGWZ:)
https://www.aavso.org/vsx/index.php?view=detail.top&oid=838181

As you can see, this likely dwarf nova (outburst) has already
been added to the International Variable Star Index.

I strongly recommend to use the designation 'TCP J21040470+4631129'.
TCP designations are for TOCP transients that are neither
(possible) novae (PNV) nor (possible) supernovae (PSN).
------------------------
The same with
https://www.aavso.org/vsx/index.php?view=detail.top&oid=838089

I would have recommended to use 'TCP J16271698+0405590' instead
of 'PNV J16271698+0405590' or 'OT J16271698+0405590'.
'TCP' at least indicates where the discovery was originally
announced; 'OT J...' is ambiguous in this regard. OTOH, when you
come across an 'OT J...' designation, you can easily guess who
made it up. ;-)
