The iCSC iPhone application downloads the current Clear Sky Chart (copyright 2008 A. Danko) image for your location. It is the astronomers forecast. It shows at a glance when, in the next 48 hours, you might expect clear and dark skies. This is a free iPhone and iPod touch application available from the Apple App Store (in the Weather category).

You must first select your site ID from the list of locations. If your location is not listed, and you have a Clear Sky Chart ID, you can enter the ID manually. Once the site is selected it will be used each time you launch the iCSC application. You can save up to 5 sites as bookmarks.

You can move the Clear Sky Chart with your finger, flip the display horizontal and vertical or display the full chart by double tapping the screen. The toolbar controls allow you to go to the site lists, refresh the chart, display the start up screen, see color descriptions, view an instruction page or see copyright information and resource web sites. A complete description of the colors can be found at the CSC web site. For support you can email Microprojects.
