This is a repository to hold all the tutorial notebooks for the data analysis day of the Solar Orbiter 8 Workshop.

The notebooks for each instrument is in their repective folders.

NOTE: For the EUI, Metis, PHI and Solo-HI tutorials accompanying data will need to be downloaded to run the tutorial notebooks. The links to download these data are within the README files in the instrument directories.

JHelioviewer tutorial

JHelioviewer can be downloaded from here: https://www.jhelioviewer.org/

The movies and he JHelioviewer states that were shown in this tutorial can be accessed here:

• ftp://omaftp.oma.be/dist/astro/Verbeeck.F/JHelioviewer movies/

Run the notebooks

Binder

These notebooks (apart from some that require external downloaded data) can be run in the browser using binder.org.

To launch this click on this link ->

Note It may take a few minutes to load up the first time you launch it.

Run locally

Here are the steps you'll need to run:

1. Download the files using git

If you want to run these notebooks locally you can clone this reposity (or fork it and then clone it from your page). To do this run this command:

• git clone https://github.com/SolarOrbiterWorkshop/solo8_tutorials.git

If you have first forked it then you can run:

• git clone https://github.com/<username>/solo8_tutorials.git

You can also download these notebooks by clicking on green code button on the top right hand side, and then by clicking download zip.

2. Create a conda environment

We recommend creating a new conda environment and install the requried packages used in these notebooks. Here is a nice introduction to anaconda environments for those new to the concept, and here is a conda cheatsheet which may help too!

The python packages required to run these workshop notebooks are listed in the environment.yml file in this repository. To create a new environment with these packages installed you can open a terminal and type:

• conda env create -f environment.yml

This will then create a new conda environment called solo8 (this name is listed in the enviroment.yml file).

You can then activate this environment by typing:

• conda activate solo8

Note your prompt should change and now have solo8 near the start. If you want to list all your conda environments you can type conda info -e. You should see base which is your base enviroment, the solo8 one, and any others you have created!

2.2 Updating the environment.yml file

If an update is made to the environment.yml file then you will need to type

• conda env update --file environment.yml --prune

This may be important after you have down a git pull (see below 4.)

2.3 Installed new packages in this environment

You can also install new packages in this environment by using conda install <package>or by using pip! (pip install <package<)

3. Start a jupyter notebook!

Once you have your environment activated (remember to first type conda activate solo8) then in your local solo8_tutorials repository type

• jupyter notebook

This should then open the notebooks in your default browser!

If you are having any issues - just make sure first that you are in the solo8 environment before you start jupyter.

Happy coding!!

4. Pulling the most up-to-date version

To make sure that your local repository reflects whats currently here you will need to run a git pull. This may be needed is you downloaded the notebooks before the 16th September. This will pull the most up-to-date version of this repository. Before you do this however, you will want to check which remote you have linked to this repository. To find out this you can type this in your local solo8_tutorials repository:

• git remote -v

and this will list the current remotes It might looks something like this

origin	https://github.com/<username>/solo8_tutorials.git (fetch)
origin	https://github.com/<username>/solo8_tutorials.git (push)
upstream	https://github.com/SolarOrbiterWorkshop/solo8_tutorials.git (fetch)
upstream	https://github.com/SolarOrbiterWorkshop/solo8_tutorials.git (push)

what you will want to do is pull the main branch from the one that is linked to https://github.com/SolarOrbiterWorkshop/solo8_tutorials - which in this example is upstream. Hence to pull the latest version of this repository you would type:

• git pull upstream main

and this will update your local files.

Otherwise if when you typed git remote -v and it looks like

origin	https://github.com/SolarOrbiterWorkshop/solo8_tutorials (fetch)
origin	https://github.com/SolarOrbiterWorkshop/solo8_tutorials (push)

then you would type

• git pull origin main

to update your local files.
