N1 - EC 20117-4014 is known to be a spectroscopic binary system consisting of an sdB star and F5V star. It was monitored using the SARA-CT telescope in Cerro Tololo, Chile over several observing seasons. Periodic O-C variations were detected in the two highest amplitude pulsations in EC 20117-4014, permitting detection of the F5V companion, whose period and semimajor axis were previously unknown.
