   Orbital period of the eclipsing symbiotic star FN Sgr

   Very recently, Brandi et al. published a paper on FN Sgr
(A&A 440, 239).  The orbital period they determined is
568.3(+/-0.3) d.  This is remarkably in good agreement
with Watanabe et al.'s value (571.5 d) published 5 years
earlier (VSOLJ Variable Star Bull. 35-36, 2), although
there is no mentioning in Brandi et al. on this earlier
study.
