1. Studying Magnetic Reconnection through Explosive Events in the Sun Hannah Alpert

2. Explosive Events in Transition Region Transition region: Sun’s atmosphere between the chromosphere and the corona – 20,000–250,000 K EEs: spontaneous energy release, detected by broadening of spectral lines

3. Interface Region Imaging Spectrograph (IRIS) Data Raster Spectral data SJI Image of Sun

4. Identifying Explosive Events

5. Making Movies!

6. Classifying the EEs Spectrum – Red – Blue – Both – Alternating – Sheared Morphology – Compact – Loop – Footpoint – Complicated

7. Loop: Compact: Red: Sheared: Classifying the EEs: Examples Spectral Examples Morphology Examples

8. Plotting the Spectra (Si IV) Velocity (km/s)

9. Analyzing the Data: Asymmetry Red and blue quartiles for each of the 82 EEs from 2014-04-15

10. Analyzing the Data: Velocity and Classifications Velocities of EEs from 2014-04-15

11. Comparing EE Types Alternating events overplotted on entire data sets from 2014-04-15 and 16

12. Comparing EE Types Compact events overplotted on entire data sets from 2014-04-15 and 16

13. Cumulative Histograms Entire data sets from 2014-04-15 and 16

14. Issues and Future Work Analyze the histograms Kolmogorov-Smirnov Test to compare different EE types More data!! Examine complicated EEs (velocities, time scales, spatial scales) Relationship to magnetic fields and reconnection
