Jupiter's great red spot doesn't appear to be in the correct position. Is there someway to reposition it?

Print Save to list E-mail Rate Article Helpful Not Helpful Created Modified Views 4188 Author Simulation Curriculum Corporation Starry Night uses a file called "JupiterGRS.txt" located in the Sky Data folder to determine the mean longitude of the GRS. To change the GRS's position you can open this file and enter a new mean longitude. The GRS drifts non-algorithmically so the GRS mean longitude will need to be updated from time to time. The latest mean longitude is available from Sky & Telescope's excellent Great Red Spot web page.
