16 Feb 2016: Lecavelier & Vidal-Madjar (2016) predict a transit between 01 Jan 2018 and 30 Jun 2018 (2 sigmas).
They find also another solution for the orbit with a transit between Jul 15 2017 and Mar 01 2018
01 May 2014: The planet has an equatorial rotation velocity of nearly 100 000 km/h (Snellen et al. 2014)
30 Nov 2011: The orbit derived from images is compatible with the putative 1981 transit event claimed by Lecavelier des Etangs et al. (1995). See Beust et al. 2011.
11 Jun. 2010: The planet image confirmed by Lagrange et al. 2010
