The amazing participants on the Solar Jet Hunter project are boxing solar jets, and here are the first results!
To “box” a jet, volunteers report the position of the base of the jets at two different times and draw a rectangular box around the jet. Each subject needs to be boxed by at least 16 volunteers before it can be marked as “completed”. An example of a boxed jet is shown below:
On this animated image, we can see both the individual classifications from the volunteers and the “average” box and base location computed from these classifications. The average box is visible in white through the animation while the individual boxes are shown in gray in the frame that was chosen by the volunteers for the annotation. Similarly, averaged positions of the base of the jet when it starts and ends are shown by a blue cross and a yellow cross respectively, while individual annotations are shown as blue and yellow dots!
This information is very useful for the solar physicists interested in jets: the position of the base, as well as the times at which the jet starts and ends, are compiled in a catalog. The size of the box indicates approximately the length and width of the jet, interesting criteria to classify jets and study different scenarios for the generation of solar jets.
We are currently working on data from the 2011-2013 seasons. 131 jets have been boxed so far but 1084 jets remain, and we need your help to get them all boxed! We can then add new seasons to find more jets!
