The material on this CD was prepared by Rachel Howe, National Solar Observatory, Tucson, to accompany a poster presented at a meeting of the Solar Physics Division of the American Astronomical Society at Lake Tahoe, Nevada, in June 2000.

This work utilizes data obtained by the Global Oscillation Network Group (GONG) project, managed by the National Solar Observatory , which is operated by AURA, Inc. under a cooperative agreement with the National Science Foundation. The data were acquired by instruments operated by the Big Bear Solar Observatory, High Altitude Observatory, Learmonth Solar Observatory, Udaipur Solar Observatory, Instituto de Astrofísico de Canarias, and Cerro Tololo Interamerican Observatory.

SOHO is a mission of international cooperation between ESA and NASA. The SOI--MDI project is supported by NASA grant NAG5-3077 to Stanford University.

RWK, and RH in part, were supported by NASA contract S-92698-F.

JC-D was supported in part by the Danish National Research Foundation through the establishment of the Theoretical Astrophysics Center.

MJT was supported in part by the UK Particle Physics & Astronomy Research Council.

JT was supported in part by NASA through grants NAG 5-7996 and NAG 5-8133, and by NSF through grant ATM-9731676.

If you use these images in public, please credit NASA and NSF's National Solar Observatory.

Images were created using IDL and the excellent free package Vis5d and manipulated with ImageMagick, another fine free package.

While this work would not have been possible without the bodies mentioned above, I (RH) would like to point out that no public funds were expended in the production of this CD! I designed it in an evening on my own PC and reproduced it on my own media, so the quantities available are limited.
