The possibility of a changing period for V1288 Sagittarii.

PLOFKER K.

Abstract (from CDS):

V1288 Sagittarii was studied using data from the Maria Mitchell Observatory and earlier published data in order to determine the accuracy and constancy of its published period. The Maria Mitchell data indicated nothing definitive about the constancy of the period, but the earlier data were open to two interpretations, one of which strongly suggested a constant period while the other pointed to a changing period.
