Chromospheric Structure and Dynamics: From Old Wisdom to New Insights

The 25th NSO Workshop will be held this fall at Sunspot, NM, USA and will focus on recent developments in our understanding of the dynamics and structure of the solar chromosphere. Increased spatial, spectral, and temporal resolution have provided many new surprises about the physical processes of the chromosphere. We also continue to learn of its complicated role as the intermediary between the photosphere and corona.

Topics to be addressed include:
- The Quiet Chromosphere
- The Chromosphere of Active Regions
- Chromospheric Magnetic Fields: Observation and Interpretation
- Filaments and Prominences
- The Chromosphere-Corona Connection

There will be both invited reviews and contributed talks in each session, but ample time will also be set aside for discussion. Space will also be available for poster presentations.

The final deadline for registration and abstract submission is June 30, 2009, but note that the workshop is limited to 60 attendees, so early registration is recommended. Note that the deadline for requesting travel support is June 1st.

Detailed information on the conference registration, abstract submission and logistics are available on the web page:

Chromospheric Dynamics and Structure: From Old Wisdom to New Insights
August 31 – September 4, 2009
Sacramento Peak Observatory, Sunspot, NM, USA

The 25th NSO Workshop will be held this fall at Sunspot, NM, USA and will focus on recent developments in our understanding the dynamics and structure of the solar chromosphere. Increased spatial, spectral, and temporal resolution have revealed many new surprises from the chromosphere and we also continue to learn of its complicated role as the intermediary between the photosphere and corona.

Topics to be addressed include:
* The Quiet Chromosphere
* The Chromosphere of Active Regions
* Chromospheric Magnetic Fields: Observation and Interpretation
* Filaments and Prominences
* The Chromosphere-Corona Connection

There will be both invited reviews and contributed talks in each session, but ample time will be set aside for discussion. Space will also be available for poster presentations.

Due to the limited space at the Sunspot meeting facilities, attendance will be limited to 70 participants.

A welcome reception will be held on the evening of Monday, August 31st, and the meeting will run through Friday, September 4th.
