Maria Mitchell Observatory,
Five known andone new
Mira-type variables were examined for period determination on Nantucket plates
taken from 1957 through 1974. All six stars were found while intercomparing
plates centered on λ Sagittarii with Nantucket's Rodman blink microscope.
V933, V935, V1289, and V1599 Sgr were re-discovered by myself in 1974 while
blinking plates for JD 41595 and 41918; V1683 Sgr and the new variable were
found by Harriet Dinerstein in 1973, comparing plates for JD 37818 and 37929.
