Overlaying differentially rotated gridlines¶
How to overlay differentially rotated gridlines on a Map.
The example uses the
sunpy.coordinates to overlay differentially rotated gridlines on
a Map. See Differential rotation using coordinate frames for more details on using
Let’s use an AIA observation, and plot lines of constant longitude in heliographic Stonyhurst. We’ll plot the normal lines (prior to applying differential rotation) in white and the differentially rotated lines in blue.

Lines of constant longitude prior to differential rotation
Differentially rotating the lines of constant longitude by 27 days Be aware that the differentially rotated lines are plotted in the original coordinate frame, so it doesn’t account for any motion of the observer over 27 days.
