Alert Notice 535: R Aqr observing campaign
Abstract:
Ongoing visual, photometric, and spectroscopic observations of R Aqr about once every 10 days are requested, both to detect and observe the next eclipse and to continue the light curve of this star.
Justification:
R Aqr is an extremely interesting system. Its type is both Mira (M) and symbiotic (ZAND) - it is a close binary system consisting of a hot star and a late-type star (the Mira), both enveloped in nebulosity. The current behavior of R Aqr suggests that the eclipse, which lasts for several years, may either be beginning or its beginning may be imminent.
