This document summarizes a presentation about solar prominences and tornadoes using data from multiple solar observatories. It discusses co-aligning different data sets to examine pixel-by-pixel correlations. Spectroscopy from Hinode/EIS provided a spectroscopic look at tornadoes. Doppler measurements showed motions within tornadoes. Images showed a tornado prominence eruption and subsequent coronal mass ejection. Upcoming Solar Orbiter and Parker Solar Probe missions were briefly described to get closer views of the Sun.

12. Co-aligning data sets
• Want to examine correlations between parameters on a
pixel-by-pixel basis
• Start by co-aligning data sets:
• AIA
• THEMIS
• IRIS SJI
• IRIS raster
• Hinode SOT
• Hinode EIS
• Co-aligned using 2D cross-
correlation

13. Co-aligning data sets
Grey = AIA 304 Å
Red = IRIS Mg II SJI
Blue = SOT Ca II
Green = EIS 256 Å
Contour = THEMIS

14. Thank you spectroscopy!
• Hinode/EIS: spectroscopic look at tornadoes
Spectroscopy
Detailed analysis
of light properties
as a function of
“colour” (ie
wavelength or
frequency)

15. Thank you spectroscopy!

18. Tornado + Prominence Eruption
SDO/AIA
193Å
23-29-Apr-2015

19. Prominence Eruption
SDO/AIA
304Å + 335Å
31-Aug-2012
19:00 - 24:00

20. Coronal Mass Ejection (CME)
Expanding magnetic “bubble”
of material breaks off into
space
– Typically a billion tonnes
travelling at million km/h (450
km/s)
If directed towards Earth can
get major geomagnetic storm
– A few days to reach Earth but
tricky to predict
SoHO/Lasco coronograph

21. ESA’s Solar Orbiter
Multi-wavelength imagers,
spectrometers and in-situ particle
detectors
– University of Glasgow
researchers involved with several
of the instruments
Launches 2020
– Gets closer to the Sun than
Mercury after cruise phase

22. NASA’s Parker Solar Probe

23. We live in the Sun’s atmosphere
