You can update your copy of CyberSky 5 to version 5.1 by using the patch found below.
Use the link below to download the patch.
The patch includes all of the bug fixes, minor enhancements, and other changes introduced since the release of CyberSky 5.
Note A full version of CyberSky 5 must be installed on your computer before you can use the CyberSky 5.1 patch. The patch won’t work with a trial version of CyberSky 5, nor will it work with CyberSky 1, 2, 3, or 4.
Installing the update
To install the CyberSky update on your computer, download the patch file, double-click the file to start the patch program, and then follow the instructions that appear.
During installation, the patch program modifies or “patches” the CyberSky program and Help file installed on your computer so that both include all of the improvements introduced in newer releases.
After you install the CyberSky update, you don’t need the patch file to run the program, but you should save it in case you need to reinstall CyberSky.
Notes about recent releases, including descriptions of bug fixes, minor enhancements, and other changes to the program are found below.
(November 22, 2016)
- You can now include multiple-line titles on printed maps, and can add any notes you feel are useful as well. CyberSky automatically adjusts the sizes of the title and note boxes to accommodate the text. As is the case with other text that appears on printed maps, you can customize both the color and the font used for notes.
- If the size of text, apps, and other items in Windows 10 was set to a value higher than the default of 100%, the map wasn’t being scaled properly in print preview. Fixed.
- You now have the option to include the day of the week in dates displayed by CyberSky, as either three-letter or two-letter abbreviations. In other words, CyberSky can now display dates like “Wed 08/10/2016” or “We 08/10/2016” on screen and on printed maps.
- The method that CyberSky uses to determine the value of ΔT has changed. For the years 1001 BC to 1700, CyberSky now uses tables of ΔT values published by L. V. Morrison and F. R. Stephenson in 2004. For the years 1701 to 2016, the program uses tables published in The Astronomical Almanac and updates from the International Earth Rotation and Reference Systems Service. For dates that fall outside the range 1001 BC to 2016, CyberSky extrapolates the value of ΔT as recommended by Morrison and Stephenson. These changes, which bring the program’s output into closer agreement with the Jet Propulsion Laboratory’s latest planetary and lunar ephemeris, DE431, will be of interest primarily to those using CyberSky for archaeoastronomy research. For more information, see the topic “Accuracy of ΔT values” in the program’s Help file.
- The distances of planetary moons from the Earth weren’t being calculated correctly, so those moons weren’t being “layered” properly on the map. For example, if Jupiter was being occulted by the Moon, it was possible for Jupiter’s moons to appear in front of the Moon. Fixed.
- You no longer have to right-click an object to edit its path displayed on the map or to delete its path from the map. You can now right-click any position along the object’s path to use the Edit path and Delete path commands.
- You can now right-click any position along an object’s path and use the new Path position time command to set the time to when the object reaches that position along the path.
- The phase of the Moon displayed in the Moon Properties dialog box now includes the appearance of the Moon: waxing crescent, waxing gibbous, waning gibbous, and waning crescent. For example, “Waxing crescent, 1.5d before first quarter.”
- The Properties dialog boxes for all types of objects now display the azimuths at which the object rises and sets, as well as the altitude at which the object transits the meridian.
- In the Seasons dialog box, the duration of each season was being displayed incorrectly for locations in the Southern Hemisphere. Fixed.
- The Twilight dialog box now displays the azimuths of the Sun at sunrise and sunset, and the altitude of the Sun at which it transits the meridian.
- If the size of text, apps, and other items in Windows was set to a value higher than the default of 100%, hovering the pointer over an object on the map resulted in a tiny window that displayed no information about the object. Fixed.
- If you changed the size of text, apps, and other items in Windows from one value to another, say from 100% to 125%, the Control and Pointer bars weren’t resized to match. Fixed.
- Removed support for the Office 2007 Scenic and Office 2007 White color schemes.
- Removed support for Windows XP.
(October 4, 2011)
- The Roman numeral designations of planetary moons—for example, Saturn VII for Saturn’s moon Hyperion—were not being displayed correctly in the Properties dialog box for planetary moons. Fixed.
- If the path of an asteroid was added to the map, the path was calculated and displayed correctly, but the current positions of asteroids weren’t updated correctly. Asteroids therefore disappeared from the map. In some cases, CyberSky would even “lock up.” The same thing happened to comets if the path of a comet was added to the map. Fixed.
- The rise, transit, and set times for meteor showers, displayed in the Properties dialog box for meteor showers, were not being calculated correctly. Fixed.
(January 4, 2011)
- If the time was set to a moment in the distant past or far in the future, a bug could cause the program to “lock up” or stop reponding. Fixed.
(November 22, 2010)
- Each time CyberSky was started, both the Control bar and the Pointer bar were placed at their default positions instead of being placed at the positions they had when the program was previously quit. Fixed.
(November 10, 2010)
- Initial release of CyberSky 5.
