Transit times for Jupiter's Great Red Spot from October 2010 through February 2011 (in Universal Time) are listed below.

These predictions assume the Red Spot is at Jovian System II longitude 157°, based on historical trends noted by JUPOS. If the GRS has moved elsewhere, it will transit 1 2/3 minutes late for every 1° of longitude greater than 157° or 1 2/3 minutes early for every 1° less than 157°.

Features on Jupiter appear closer to the central meridian than to the limb — and thus are well placed for viewing — for 50 minutes before and after their transit times.
