Bastille Day 2000
This profile shows the Coronal Mass Ejection (CME) that occurred on Bastille Day, July 14, 2000. The profile is data heavy and will require a powerful graphics card (GPU).
Tour
This profile includes many different visuals, so to avoid cluttering the scene, it is recommended to use the provided keyboard shortcuts to toggle elements on and off.
This CME event might be the most studied solar storm so far. The visualizations to highlight the CME include:
A volume rendering of the density of the material ejected from the Sun
Field lines showing the Sun’s magnetic structure
Magnetograms which are texture layers on the Sun showing variation in strength of the magnetic field,
An extreme ultra-violet (EUV) image sequence layer shown on the Sun
A speed of light indicator to compare the speed of the CME
Cut-plane sequences showing the proton intensity (flux values) of the CME, one equatorial cut plane and one meridiona,
Flux nodes that also show the proton intensity (flux values), which are accompanied by a legend describing the color scheme. Flux nodes are simulated points positioned along the magnetic fields where the flux values are calculated

To better show the CME event, a few different time loops have been implemented with different start and end times and differences in how fast time is sped up:
Shortcut |
Function |
|---|---|
CTRL+1 |
For a short loop. 10:03 - 10:16, at 2 min/ econd. Recommended for close-up view of the Sun |
CTRL+2 |
For the “standard” loop. 10:03 - 11:00, at 4 min/second. A generally good loop showing most of the event at a good pace |
CTRL+3 |
For a fast loop. 10:03 - 11.48, at 15 min/second. In case something particular will be showcased over and over |
CTRL+4 |
For a long loop. 09:30 - 13:00, at 4 min/second. Starting earlier and ends even after some of the data sets no longer have data at those time steps |
r |
To cancel looping and reset the time to 10.03 |
Data Sets
The visualizations of the solar corona in this profile are provided by Predictive Science Inc. (PSI) simulation model MAS/CORHEL for the corona visualizations. The EPREM model is used for the flux visualizations. The EPREM model was developed by the Young-Schwadron modeling group at the University of New Hampshire.
