Great Red Spot Transit Table Sept 2013 – May 2014

Transit times for Jupiter's Great Red Spot (GRS) from September 2013 through May 2014 (in Universal Time) are listed below.

These predictions assume the Red Spot will be at the following Jovian System II longitudes:

201° in September 2013
202° in October 2013
203° in November 2013
205° in December 2013
206° in January 2014
207° in February 2014
208° in March 2014
209° in April 2014
210° in May 2014

These are a good match for the GRS's behavior over the last few years, as noted by JUPOS. If the GRS has moved elsewhere, it will transit 1 2/3 minutes late for every 1° of longitude greater than the assumed longitude.

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.
