2nd ATST - EAST Workshop

Magnetic Fields from the Photosphere to the Corona

9 – 11 November 2011, Washington, DC


This workshop focuses on connectivity science that looks at the solar atmosphere as a systemconnected by solar magnetic fields. Particular emphasis will be on discussing the new capabilities that large aperture solar telescopes will provide for observing and measuring magnetic fields and their dynamic behavior from the photosphere to the corona. This 2nd joint ATST-EAST workshop continues to demonstrate the common interests of the European and US solar physics community toward next-generation, large-aperture solar telescopes. While this workshop focuses on the science drivers behind large aperture telescope efforts, significant time will be allotted to discuss ongoing and future telescope and instrumentation efforts and give an opportunity to present techniques and tools that are vital for scientific exploration using new facilities.

Program Outline

1. Magnetic Fields from the photosphere to corona. Topics include: Magnetic field measurements connecting different layers of the atmosphere. Multi-height Observations of the dynamic Photosphere-Chromosphere-Corona System. Observational signatures of the heating of the upper atmosphere. Modeling of magnetic fields – photosphere, chromosphere and corona. Comparison of models and simulations with observations.

2. New telescope and instrumentation efforts: In this session, several large-aperture telescope projects and new instrument concepts and developments will be presented. Adaptive optics for large aperture solar telescopes. Large aperture coronagraphs. Discovery potential of 4m-class telescopes. Coordination of ground-based and space telescopes as a tool to help understand the 3D magnetic structure. Data storage, distribution, and exploration systems.

3. Tools and techniques: Polarimetric analysis of the solar magnetic field. Measuring and interpreting magnetic fields in the solar atmosphere. Inversion techniques. Magnetic field extrapolation techniques. Data acquisition, analysis and interpretation methods.


On-line registration will be possible through the conference web page. A minimal conference fee of 150 $ will be charged in order to offset the cost of proceedings, refreshments during coffee breaks, internet access (wireless), and the conference dinner. The deadline for online registration is 30 September 2011.


Please consult the conference web page for details.


We plan to publish all workshop contributions as refereed conference proceedings in the Conference Series of the Astronomical Society of the Pacific.

The publication date will be May/June 2012.

Details about submission and deadlines of manuscripts will be provided on the conference web page soon
