NSV 11154: A newly classified R CrB star
A paper by Nutsinee Kijbunchoo (LSU) and others on the star NSV 11154 has just been accepted for publication in the Publications of the Astronomical Society of the Pacific. This paper "NSV 11154 is a New R Coronae Borealis Star" is now available on arXiv.org, and makes use of observations old and new.
AAVSO Director Arne Henden contributed some of the "new" observations made with the Sonoita Research Observatory telescopes, part of AAVSOnet, over the past year. The paper contains some important "old" data as well -- photometry from the Harvard Plate Collection by the DASCH project, which is seeking to digitize and photometer the vast Harvard plate archives.
