In 2006, an extrasolar planet was discovered orbiting HD 224693 by the Keck telescope using radial velocity measurements. A preliminary search for transits using photometric data from Fairborn Observatory was inconclusive because data around the predicted time of transit was to sparse to rule out possible transits.[2]
