R Aquarii is a stellar system containing a long-period (386 days) Mira variable of spectral type M7e. The presence of an irregularly variable blue continuum and possibly of a several years modulation in the lightcurve suggests that the Mira has a companion, namely a white dwarf with an accretion disk. The most spectacular feature of this symbiotic system is a brigth circumstellar nebula (photographs of which are shown in Sky and Telescope, 64, 141, 1982 by Kaler). This nebula is very likely due to a nova outburst undergone by R Aquarii centuries ago and described in Japanese astronomical records of AD 30 (Kafatos, Michalitsianos, Nature, 298, 540, 1982).
