Week 5
The goal of my research project was to analyse the shear of flare loops over time. Therefore, I wanted to look at the 171A AIA movie to determine the cut off points. To determine where the shear was changing more rapidly or if it was more constant over time. I also needed the exact start time of the flare loops appearing. I also needed to redo the movies so that they would show the time progression as part of the map labels. This meant going back and re-running the png creation code again.
I decided to only take loops until 18:00UT as the loops after that do not change much and the light intensity curves suggest that the flare activity is over.
I also re made the 335 movie. I subtracted the background light as taken from the thrid frame. Then I did the same process as with the 171 to create a movie that shows the flare observations over time. I saw that the 335 loops started earlier at 15:42 not 15:49 UT.
While out exploring, I saw two different trout in the small stream by the Gallagator Trail.



Week 6
This week was cut short because of the 4th on Thrusday. I finished tracing all of the loops and saving the five sections into one merged file. I discovered that the places where I split the 171 and 335 movies were not quite where the shear was changing. Therefore, all of the individual saved loop files had to be merged together. I created a program that could merege all of these automatically for me.
The other program I worked on this week was plotting the falre loops over the flare ribbons rather than having the AIA images as the backdrop. This made it easier to compare the observed loops to the models that were also plotted over the flare ribbon pixels.
My final project of the week was finally to calculate the shear of the loops. Shear is 90 degrees minus the angle between the polarity inversion line and the angle of the loop. Past observations have not been able to calculate this phenomonon in multiple wavelengths or with as many loops as I was able to get for this project. I have included the graphs of the shear as a function of position along the PIL. Although 94A was not calculated until the week before the Hinode Confrence, I have included it for comparison. Note that the 171 has a different axis than the other 2.

No presentation for these two weeks because it was the Fourth of July. My Mom came out to visit and we went on several hikes around including Storm Castle, Hyalite Lake, and South Cottonwood Trail.
