Maria Mitchell Observatory,
I first observed VX
Sagittarii while blinking two plates of the region taken at Nantucket. The star
was originally discovered by henrietta Leavitt in 1904, and has been on the
AAVSO observing program since 1935. I was originally interested in comparing
its photographic and visual light curves. VX Sagittarii isa semiregular varible
with an extremely long period.
