V744 Centauri, is asemi-regular variable pulsating star in the constellation Centaurus. Located 3 degrees north north east ofEpsilon Centauri, It ranges fromapparent magnitude 5.1 to 6.7 over 90 days.[3] It is unusual in that it is a red star with a high proper motion (greater than 50 milliarcseconds a year).[4] When it is near its maximum brightness, it is visible to thenaked eye under good observing conditions.
In 1964,Wolfgang Strohmeieret al. announced the discovery that the star is avariable star.[5] It was given itsvariable star designation, V744 Centauri, in 1968.[6]
