A keyword search on SY Cir at the ADS gives this abstract link:-

http://adsabs.harvard.edu/cgi-bin/nph-bib_query?bibcode=1997BaltA...6..133D&db_key=AST&high=390983001612865

[which will have wrapped in transmission].

The full article is not available online, unfortunately, for me to check
whether the southern star SY Cir is actually mentioned fully in this
copy of Baltic Astronomy Vol 6 p133 [Author Dennis W Dawson, 1997].

The following snippet showing the abstract *suggests* that SY Cir has
been examined re variability type in this paper, however.

Anybody got a non-ecopy [you know, paper and ink]?
