(1) The First LWS Solar Dynamics Observatory Science Workshop, May 3 - 6, 2011, Lake Tahoe, NV/CA (exact location still under consideration). From Barbara Thompson ( See also

"Solar magnetic activity from large to small: Scales, couplings, and cascades from the solar dynamo into the Sun's atmosphere and heliosphere"

Living With a Star's Solar Dynamics Observatory invites you to its First Science Workshop, to be held May 3 - 6, 2011 in the Lake Tahoe area. The theme will be "Solar Magnetic Activity from Large to Small," and will address science questions that are fundamental to all three of SDO's science investigations:

  • Atmospheric Imaging Assembly (AIA)
  • EUV Variability Experiment (EVE)
  • Helioseismic and Magnetic Imager (HMI)

The meeting will consist of both plenary sessions and working group/discussion sessions. All members of the science community are welcome to attend.

The meeting sites are being investigated, and the precise location will be determined in mid-October. Updates will be posted to the meeting website, which will be launched in late September:

Description of Meeting Theme:

Solar magnetism forces us to view the Sun, its atmosphere, and even the inner heliosphere as a single coupled system from the deep dynamo to the solar wind. The high resolution and global view of the Solar Dynamics Observatory, in conjunction with other ground- and space- based instruments and supported by advanced data-assimilation and modeling techniques, provide a new opportunity to study solar phenomena from near the resolution limit to the global scale, and how these are connected among themselves.

Within the broader context of the wide-ranging advances being made in solar and inner-heliospheric physics, this meeting aims to emphasize some long-standing problems to which SDO can uniquely contribute: What is the origin of self-similar behavior and power-law distribution functions for emerging bipolar regions, for flares, and for eruptions from small fibrils to large coronal mass ejections, and where and why does self-similarity break down? Why and how do distant regions interact, and how far do these interactions reach across the Sun? How, how fast, and how far do emerging bipolar regions interact with the atmosphere into which they rise? What role do large-scale field changes play in triggering or preventing impulsive and eruptive events,and vice versa? How do changes in field and plasma properties near to and distant from flares and eruptions determine global spectral irradiance variations?

We are looking forward to seeing you in Lake Tahoe.
