SOHO: Exploring the Sun - an interactive CD-RO


SOHO: Exploring the Sun is an interactive, multimedia exploration of the Sun through the eyes of SOHO, the Solar and Heliospheric Observatory. Through clever and engaging interface features, the most recent developments from SOHO in solar exploration are presented through text, graphics, animations and video clips. The CD includes over 100 movie clips, over 400 images, web links, an extensive glossary as well as soundtracks specially composed for this CD.

The CD is organized into three main sections, which also have subsections: A New View of the Sun (covers topics from the solar interior to CMEs to the solar wind); The Sun (includes a history of solar exploration, the Sun-Earth connection, and some general information); and SOHO (the mission, instruments, results, and a complete presentation of highlights). In short, this is the most complete and dynamic overview of the SOHO mission to date.

HAVING PROBLEMS? Technical support and FAQ's

Here follows some typical problems some users have encountered.

Q: I started the program but after the initial screen it leaves me with a blank screen. What is wrong?

A: Try to run the program from the DATA-directory, by clicking the SOHO.EXE - projector icon there.

Q: Some of the movies and features of the CD-ROM does not work properly.

A: Most probably a MINIMAL version of Quick Time was already installed on your computer. To run the CD properly the FULL QT4 INSTALLATION is required. The default installation is MINIMAL (or NORMAL), which WILL NOT WORK. Please reinstall QT4 with FULL INSTALLATION. QT4 is included on this CD.

Below you will find more information about this issue and how get technical support.

The CD-ROM will check if you have QT4 installed. If not it will install it for you. However, if you already have the minimal QT4 installation on your computer the CD-ROM will assume everything is OK and skip the QT4 installation. If you encounter problems playing movies please check if you only had the MINIMAL INSTALLATION QT4 on your computer, and reinstall QT4 from the CD-ROM.
