Capacity Building & Cross-Disciplinary Education
Selecting a Grand Challenge Problem in Heliophysics Provides Focus
Final Selection of Questions:
AR 798 anemone active region. [Ayumi Asai, NSRO, 2005]
Produced CME with high velocity; high dynamic pressure in the sheath
A major substorm was triggered just as the IMF Bz reached it’s minimum values
Unusual auroral oval configuration with large vortex on the dawn side and double oval structures (possibly another vortex) on the duskside. Thick nightside oval & very thin dayside oval. [Kozyra et al., Spring AGU, 2006]
Evidence for new type of storm-substorm coupling
20 Aug 2005, 00:50 UT Anemone Active Region [Asai, Stanford Workshop, Dec. 2005]
[Kozyra et al., Spring AGU, 2006]
Underlying physical processes?
Explain some of the unusual features of superstorms?
Is this a new form of storm-substorm coupling?
IONOSPHERE - ATMOSPHERE
How do these large current vortices effect the state of the ionosphere-atmosphere
Strong sources of Joule heating?
Produce upwelling or other feedbacks to the magnetosphere?
SUN & HELIOSPHERE
What effect does close proximity to an active region have on the release & propagation of CMEs?
Does an active region leave a “fingerprint” on the CMEs? Do they have common characteristics?
How important were propagation?
How important is the duration of the IMF Bz in how energy is apportioned?
Are there truly supersubstorms that represent a new state of the magnetosphere?
Effects of super-substorms throughout geospace?
Website for CAWSES Virtual Poster sessions is under development at JHU/APL
