We show that as PU Vul fell to full quiescence in 1994, following a long ou
tburst, the system developed well-defined 0.2 mag oscillations with a chara
cteristic period of similar to 211 days. This quasi-periodicity is distinct
ly different from the behavior seen during late decline from outburst, wher
e weaker photometric variations near 317, 227, and 120 days were seen. Sugg
ested causes for this variation are discussed.
