Title

Drift in System 2 Longitude GRS Years 2011 -2024

About this image

Here is a graph I compiled of 111 transit timings of the Great Red Spot from 2011- 2024. If you enlarge the graph you can see the individual data points on the graph. There were a few timings that were based on estimates because of seeing degrading or clouds interfering. All timings were made visually in the telescope with the usual magnification of 171x. When seeing permitted higher magnifications were used. There were timings I made of the preceding and following end of the GRS but these are not shown on the graph. The GRS in the 2023 apparition was the smallest I've ever seen.

I'm looking forward to the 2024 apparition and continuing with this project.
