The XO Project is a photometric search for Jovian planets transiting very bright stars.
Ephemerides for Known Transiting Planets (caveat: the rate of discovery sometimes makes it hard to keep this up to date. Please pick a site near yours - predictions should be adequate for planning observation but should not be used for analysis as these ephemerides are not maintained accurately.)
