Solar Image Processing Workshop V – Second Announcement

Second Announcement

Fifth Solar Image Processing Workshop

Eurotel Victorio, Les Diablerets, Switzerland
September 12-16, 2010

This series of workshops brings together members of the solar physics and image processing communities to present and discuss advances in solar image processing techniques. The design and implementation of existing algorithms as reliable and robust tools are discussed, as well as automated techniques for processing very large amounts of data.

The fifth Solar Image Processing Workshop will concentrate on the role played by solar image processing as we enter the petabyte era of solar physics. For example, the Solar Dynamics Observatory vastly increases the amount of data we have about our Sun, and solar image processing is taking a central role in reducing SDO and other data into useful information about the underlying physics. We are pleased to confirm at this time two invited speakers – Piet Martens (Harvard-Smithsonian), discussing the SDO Science Center and the image processing techniques being used there, and Michaele Piana (University of Genoa), discussing inverse problems in relation to image processing.

The structure of the workshop is as follows. The morning is given over to talks presentations, with all breaks also being poster sessions. Participants are expected to attend all talks and poster sessions. In the afternoons, the conference splits into splinter sessions, where the following subject areas are covered. We solicit contributions in these areas.

(1) Solar Eruptive Events

This session examines solar eruptive events of all types such as flares and coronal mass ejections, including:

  • detectable precursors
  • automated tracking of events via image processing algorithms
  • physics of eruptive events
  • energy and mass storage in the corona
  • flow into the extended solar atmosphere
  • prediction of eruption

(2) Solar Disk Features

This session deals with all types of features and events on the solar disk and how they may be tracked in time, space and wavelength.

Topics of particular interest are:

  • prediction of the emergence of active regions
  • automated tracking of features in time, space and wavelength during their passage across the disc.
  • cataloging of features and the comparison of feature catalogs
  • detection of changes to solar features with time as precursors to shorter time-scale behavior such as flares and prominence eruptions.
  • physics of sunspots, coronal holes, filaments/prominences and other solar features

(3) Reconstruction of the 3-D solar atmosphere

This session deals with the reconstruction of the true structure of the solar atmosphere from multiple viewpoints, wavelengths and times.

Topics of particular interest are:

  • reconstruction of the three-dimensional dynamics of coronal mass ejections as a function of time
  • propagation of 3-dimensional structures in the extended solar atmosphere
  • three-dimensional structure of coronal magnetic fields
  • changes in three-dimensional structure in time as a precursor to subsequent events

(4) Differential emission measure, solar activity and irradiance reconstruction

This session deals with the differential emission measure (DEM) of various solar features; how solar activity changes the DEM, and the reconstruction of the solar irradiance spectrum from the spatial features we see on the Sun. Topics of particular interest are:

  • DEM reconstruction methods
  • using DEM to recover the physics of solar features
  • connecting DEM to the observed spatial and temporal behavior of solar features
  • reconstruction of the irradiance spectrum.

VERY limited funding is available for students who wish to attend the conference. Please contact the Chair of the Science Organizing Committee ( stating

  • name
  • institution
  • proposed contribution (title + abstract + presentation type – talk or poster)

Students will be selected for funding on a first come, first served basis and on the suitability of their work with respect to the stated areas of interest of the workshop.

Registration is now open at

We have negotiated a special rate at the conference hotel; for CHF230/night ($200, EUR165, GBP136) we provide accommodation, breakfast, lunch, dinner and coffee/tea for the duration of the meeting. The meeting location is in a village in the Swiss Alps, so alternative accommodation is sparse. Participants are strongly encouraged to register at the conference hotel to take advantage of this rate.

If you have any further questions please do not hesitate to contact the SOC and LOC chairs at the email addresses below.

See you in Switzerland in September!
