New game ‘Trace It’ released along with more ‘Spot’ data

The long-awaited new game ‘Trace it’ is released today and represents a rolling up of the metaphorical sleeves as we seriously get into analysing the data from the NASA STEREO mission. Thanks to all your efforts with the ‘Spot’ game we have now identified the solar storms in the STEREO HI data up to February 2010. In ‘Trace it’, we use the information you gave us about the start time of these storms and mark these times on a more abstract data product that solar scientists call j-maps (the reasons are somewhat convoluted but we like to think ours are named after Jackie who is the person responsible for creating them).

In these plots we have taken slices through a sequence of images and stacked them to produce a collage of distances versus time for each storm, which appears as gently curling lines on each j-map. We do this because the edges of storms are sometimes difficult to pick out in the images but the human brain is very good at picking out lines in an image. In ‘Trace it’ we ask you to mark points along each storm track. By running your points through our analysis programs here at the Rutherford Appleton Laboratory, we will be able to calculate a more precise speed and direction for each storm. Once you have become used to this new way of looking at the data, we want to move on to viewing the real-time data in the same way, and then the fun really begins 🙂

Don’t think we’ve finished with the ‘Spot’ game though, we have uploaded all the movies since February 2010 and, as you will have seen in the fuzzy real-time data, there have been quite a few new storms lately. You may have thought it was insanely active already but the Sun is only just beginning to wake up so hang on, it’s going to be an interesting ride and we need you more than ever if we are going to keep up!

Thanks again for your efforts so far,

Chris
