ISEN-ASTC-L is a service of the Association of Science-Technology Centers
Incorporated, a worldwide network of science museums and related institutions.
*****************************************************************************

Though not meant for traveling, we created a digital heliostat,
basically consisting of a large table with a data projector overhead.
We download daily images of the sun in ultraviolet, x-ray, and visible
wavelengths and the user can scroll through them using a joystick.  The
user selects which wavelength they want to see using buttons.  The only
downside is that occasionally we'll miss a few days due to satellite
problems.

We didn't have enough clear days in Iowa to justify a real heliostat,
besides, roof penetrations are very expensive!
