That should be "Raa8" according to SAN (as part of the PGN standard):
|8.2.3.4: Disambiguation
|
|In the case of ambiguities (multiple pieces of the same type moving to the same
|square), the first appropriate disambiguating step of the three following steps
|is taken:
|
|First, if the moving pieces can be distinguished by their originating files,
|the originating file letter of the moving piece is inserted immediately after
|the moving piece letter.
Just a hint.
