WG4: Multi-wavelength Observations

Group Leader: Ryan Milligan
Co-Leader: Lyndsay Fletcher

The Presentations

(please contact the respective authors for questions or requests to use any content)

This aim of this working group is to highlight the scientific advances that can be made by combining RHESSI observations with those from other longer wavelength instruments (e.g. those onboard Hinode, STEREO, GBOs and now SDO). Topics will include (but are not limited to):

  • flare-CME relationship
  • coronal HXR sources
  • chromospheric/HXR observations
  • radio emission

Participants are invited to outline their efforts in these areas in recent years, and are encouraged to highlight any outstanding issues and how they may be addressed using multi-wavelength observations during the increase in activity during Cycle 24.

Working group 4 draft schedule (subject to change)

In keeping with the informal nature of the workshop each speaker will be allotted 20 minutes (10+10) for their presentation. Discussion during each presentation is strongly encouraged.
