It ranges between apparent magnitude 5.1 and 14.4, and spectral types M1IIe to M4IIe, over a period of 168 days.{{cite web|url=http://www.aavso.org/vsx/index.php?view=detail.top&oid=26334 |title=R Pictoris |author =Otero, Sebastian Alberto |date=7 June 2011 |work=AAVSO Website|publisher=American Association of Variable Star Observers|accessdate=23 May 2014}} It should be faintly visible to the naked eye of an observer with excellent observing conditions, when it is near its maximum brightness.

In 1895, Williamina Fleming discovered that the star is a variable star. In 1907 it appeared with its variable star designation, R Pictoris, in Annie Jump Cannon's Second Catalog of Variable Stars.
