Jet hunters are amazing: 20,000 classifications and counting!

Two weeks after the launch of the Solar Jet Hunter project, more than 20,000 classifications have already been achieved by the jet hunters! On top of it, hunters are discussing their classifications in the talk board, reporting multiple jets or pointing to particularly interesting events, which is of great help for the researchers.

At the launch of the project, we started with the workflow “Jet or Not”, which contained 3937 subjects: jet hunters were so efficient that this workflow ran out of data in less than 3 days! The result? Jets were found in 1213 of the initial subjects (about 31% of the subjects).

But that is not all! The 1213 subjects with jets are now being analyzed by the jet hunters in more detail, in the workflow “Box the jets”.

Indeed, solar physicists would really like to know where the jet is launching from, and what direction and size they have. That is the purpose of “Box the jets”! The tasks in this workflow are more involved: we ask the participants to mark the base of the jet in the first and last frames in which the jet is visible, and to draw a box around the jet in the frame in which it’s best visible. One can rotate the box to make fit best the jet, as seen in the image below.

Boxed jet!

“Box the jets” has been open since Dec 8 and jet hunters are doing fantastic, with more than 6000 jets boxed so far! 

Each of the 1213 subjects should be boxed by 16 different participants for the classification to be completed, so we still need a lot of help to box the jets! Based on the activity in the past few days, the Zooniverse predicts that the project should be completed by January 20. But… maybe it could be done even sooner? Jet hunters, are you up for a challenge? Can we complete the classification for this data set by January 11*?

When this first data set is completed, there will be… more data! Indeed, the first data set provided in the Solar Jet Hunter was data from the Solar Dynamic Observatory (SDO) taken between 2011 and 2013. But the SDO mission is still up and running, so we have a lot more data to look at! When the first data set is completely analyzed in “Box the jets”, we will upload more data for both “Jet or Not” and “Box the jets” workflows. 

To get this new batch of data in the project by January 11, let’s finish the classification for the first set and go #boxthejets!

*If you are wondering why January 11 specifically, that is because it would be a great birthday gift for one of the researchers in the team!
