The long-term light curve of RY Sgr has been published as an AAVSO Monograph. Available in two increments, AAVSO Monograph 5: RY Sagittarii - and Monograph 5, Supplement 1: RY Sagittarii - provides the light curves of RY Sgr for more than years. RY Sgr light curve Colonel Ernest Elliott Markwick first came across what became known as RY Sagittarii during searches for variable stars while posted in Gibraltar. [6] He recorded it dimming from magnitude 7 in July to fainter than 11 by 23 October that year, and brightening to magnitude by November [7]. RY Sagittarii light curves - Article. Jan ; J. A. Mattei; E. O. Waagen; E. Grant Foster; This monograph contains light curves of RY Sgr from through , the AAVSO historical. This supplement contains computer-generated light curves of the R Coronae Borealis star, RY Sagittarii, from through , bringing the light curves published in an earlier paper, -

R Coronae Borealis is a low-mass yellow supergiant star in the constellation of Corona is the prototype of the R Cor Bor class of variable stars, which fade by several magnitudes at irregular intervals. R Coronae Borealis itself normally shines at approximately magnitude 6, just about visible to the naked eye, but at intervals of several months to many years fades to as faint as.

RY Sagittarii (RY Sgr / HD / HR ) és el nom d'un estel variable de la constellació de Sagitari.

Visual light curve for RY Sagittarii, –, showing classic behaviour for this type of variable An R Coronae Borealis variable (abbreviated RCB, [1] R CrB [2]) is an eruptive variable star that varies in luminosity in two modes, one low amplitude pulsation (a few tenths of a magnitude), and one irregular, unpredictably-sudden fading by.
