Using Velocity and Intensity helioseismic data for improving
our knowledge of the Solar interior. (PNPS)
C. Barban, F. Hill (NSO).
Helioseismology, the study of the solar global oscillations, seeks to
infer the properties of the solar interior from the oscillation mode
parameters, primarily the frequency. The parameters are typically
determined by using the observed Doppler velocity (V) data, neglecting
the information contained in the total intensity (I) data. This
information content is demonstrated by qualitative differences
(frequency shifts, reverse mode line asymmetry) which are likely to
arise from the excitation mechanism. We present here our current work
about the use of both I and V data for improving the mode parameter
estimation and then our knowledge of the solar interior and also for
providing new measures of the excitation.

PROJECT ASTRO-TUCSON: THE ART OF LEARNING ABOUT THE COSMOS AROUND US. (Enseignement).
Caroline Barban (NSO), Connie Walker, Stephen Pompea (NOAO).
The Project ASTRO,"Astronomers and Educators as Partners for Learning",
is a national program in the USA to improve science education in grades
4-9 (CM1-3eme in the French system). This project, developed by the
Astronomical Society of the Pacific in 1993, is present in a dozen
regional sites around the United States and, in particular, in Tucson,AZ
(http://www.noao.edu/education/astrotucson.html). Project ASTRO-Tucson
matches professional and amateur astronomers with teachers and community
educators who want to enrich their astronomy and science teaching. The
project's emphasis is on a hands-on, activities-based approach to excite
students about astronomy and help them learn the process of science.
