Occult version 4. http://www.lunar-occultations.com/iota/occult4.htm This is the IOTA's recommended software for predicting lunar occultations and grazes. An extremely cool piece of software. For Windows XP and Vista users, requires pre-installation of Microsoft .NET framework 2.0 or higher and Microsoft Visual J# runtime package discussed at the Occult4 website above. Most Windows XP machines and Vista machines have Microsoft .NET 2.0 or higher installed. You will only need to install the Visual J# runtime package for installing Occult4. This software is used to predict lunar grazes and or lunar occultations of double stars between 1" and 0.1" in separation. Such stars cannot be separated visually and usually are not spectroscopic binaries. The newest version of Occult has many new features that integrate it with Google Earth and Google Sky. On my Windows XP install, the Google Earth options did not activate within Occult4. To repeat. This is one cool piece of software. - Kurt _______________________________________________ Sent via CSolutions - http://www.csolutions.net
