Hello solar jet hunters! We hope you had a great summer. In the research team, we were following your progress on classification, and you did an amazing job again at finding and boxing jets on the Sun! Thank you so much for your participation and your enthusiasm about our project. As you may have seen, we ran out of data in early August. With this post we would like to give you a short overview of what has been achieved so far, but also telling you that new data has been loaded to the project, and that once again, we need YOUR help to find and box solar jets!
Solar Jet Hunter so far…
The project was launched on December 7 2021 with 3937 subjects to be analyzed. This data set was completely analyzed by the amazing solar jet hunters by early February 2022. Since then, the data scientists of the team have been working on aggregating the results together. Preparing the subjects and interpreting the results was also the subject of the master thesis of Paloma Jol, from the University of Leiden (Netherlands) during the 2021-2022 school year. Here is a preview on Paloma’s results:
Using all the classification you provided during the first run of the project, Paloma identified 429 jets. This is amazing! These 429 jets happened in the years 2011 to 2013, which means that we can find many more! Since you boxed all of these jets, we know how big they are and their position on the solar disk: below you can see a summary of the positions of all the jets!
You can see that jets are not randomly distributed on the disk: that is expected! Many jets occur in active regions, and active regions are generally located in two bands just above and below the equator. It is also common to see polar jets, happening near the poles: those jets are not connected to active regions. Although it was not unexpected to see such a distribution of jets, it was really great to us to see that the jets you found were distributed in expected places on the Sun. We will now investigate their connection with other features on the Sun. Paloma also looked at other properties of jets such as their size and duration, and we are preparing a blog post to give you more details, it should be out in a few weeks, stay tuned!
In April we launched the project with new data from years 2014-2015. Paloma prepared the data, which consisted of 2897 subjects. Again, you, the amazing solar jet hunter, did a great job at classifying the jets in this data! The classification has been finished early August and we will soon add those jets to our catalog! But, just for you now, here are three great examples of what was found in the data by the volunteers:
Solar Jet Hunter now: we still need your help!
Now that we are back from the summer we are starting again Solar Jet Hunter, with again more data! The year 2016 was apparently rich in jets, since we have 2831 subjects to analyze in that single year alone… So will you help us and join the hunt for solar jets? We certainly hope to see you soon on Solar Jet Hunter!
