The predictions assume the Red Spot is at Jovian System II longitude 114°, the most recent value (as of July 5, 2006) provided by John W. McAnally of the Association of Lunar and Planetary Observers. If the GRS has moved elsewhere, it will transit 1 2/3 minutes late for every 1° of longitude greater than 114° or 1 2/3 minutes early for every 1° less than 114°.
