StarPlot allows you to view three-dimensional perspective charts of stars. Check the Web site to get more star data sets.

Sunclock is an X11 application that displays a map of the Earth and shows the illuminated portion of the globe. In addition to providing local time for the default timezone, it also displays GMT time, legal and solar time of major cities, their latitude and longitude, the mutual distances of arbitrary locations on Earth, the position at zenith of Sun and Moon. Sunclock can display meridians, parallels, tropics and arctic circles. It has builtin functions that accelerate the speed of time and show the evolution of seasons. Sunclock can be internationalized for various western languages. It is possible to customize the app-default file and enter additional city entries. Sunclock can commute between two states, the "clock window" and the "map window". The clock window displays a small map of the Earth and therefore occupies little space on the screen, while the "map window" displays a large map and offers more advanced functions. The Sunclock package includes a resizable and zoomable vector map. External Earth maps can also be loaded.

Tkgeomap is an open source set of extensions to the Tcl/Tk scripting language. It adds commands that read, manipulate, and display geographic data. It provides four packages: * tclgeomap - library written in C adds commands for basic geography calculations and data access. * tclgeomap_procs - library written in Tcl adds procedures that supplement tclgeomap. * tkgeomap - library written in C that adds the ability to draw maps * tkgeomap_procs - library written in Tcl adds procedures that supplement tkgeomap. This port contains the Tcl part.

"WCSLIB is a C library, supplied with a full set of Fortran wrappers, that implements the "World Coordinate System" (WCS) convention in FITS (Flexible Image Transport System). It also includes a PGPLOT-based routine, PGSBOX, for drawing general curvilinear coordinate graticules and a number of utility programs." - from README file.

This command-line utility is intended to provide quick access to current weather conditions and forecasts. Presently, it is capable of returning data for localities throughout the USA by retrieving and formatting decoded METARs (Meteorological Aerodrome Reports) from NOAA (the USA National Oceanic and Atmospheric Administration) and forecasts from NWS (the USA National Weather Service). The tool is written to function in the same spirit as other command- line informational utilities like cal(1), calendar(1) and dict(1). It can retrieve arbitrary weather data via specific command-line switches (station ID, city, state), or aliases can be configured system wide and on a per-user basis. It can be freely used and redistributed under the terms of a BSD-like License.

WeatherSpect provides a reasonably accurate simulation of what the weather looks like outside, in ASCII art. It includes rain, snow, lightning, sleet, and hail. The windspeed and cloudiness are reflected in the velocity and quantity of clouds. There are trees that age, reproduce and die over the course of an hour, and a sun and moon that follow the actual sun and moonrise. There's also a dancing turtle.

This dockapp shows you the actual distance of Jupiter in astronomical units (AE) and when the red spot crosses (which is a weather feature on Jupiter). The four Galileo Moons are displayed too but only when they are near the planet (Io, Europa, Ganymede, and Callisto). The position of the red spot changes on the surface so you need to change that value within few months or so. The current position can be found on the Internet. It was 80 deg. as of 11th Jan 2002.

This is a WindowMaker dockapp that displays a graphical representation of the phase of the moon, plus additional astronomical data such as rise/set times, orbital data, orbital elements, etc (if you click on the image multiple times). Probably most of the data is not that useful, but what the heck :)

It shows you the solar system viewed from top (90 heliocentric). The objects have the following colors: Sun - yellow Mercury - green Venus - white Earth - cyan Mars - red Jupiter - gray Saturn - green Uranus - pink Neptune - cyan Pluto is not included since it's way "off course" A left click on the window changes the view between inner and outer planets. A left click on the date increases the day/month/year. A right click on the date does the opposite. Click the right mouse button on the solar system to reset the date to the current date (which is in Universal Time).
