Example Gallery¶

The gallery contains examples of how to use sunpy. Each example is a short and self contained how-to guide for performing a specific task.

Sample data¶

Some of these examples require the SunPy sample data, which are downloaded as needed via the module sunpy.data.sample. If you want to download all of the sample data files in advance, call sunpy.data.sample.download_all().
