In April 2010, the Spitzer Space Telescope was used to search for the transit of this planet across the face of its host star. The initial light curve was consistent with a transit, however new observations with Spitzer in September 2010 did not confirm the transit signal. Analysis of both Spitzer light curves showed that the possibility of a transit was only 0.24% compared to 9.7% prior to these observations.[4]
