In October 2012, astronomers at the Palomar Transient Factory in California measured a period 13.717 hours with an amplitude of 0.11 magnitude in the R-band (), which seems to be an alternative period solution (1:2 alias) of what the Australian astronomers had previously measured. Previous observations by Gino Farroni and by Federico Manzini from 2004 and 2005, respectively, have been provisional and of poor quality ().
