You enter the date, time, geographical location and get back sky positions. Sky positions include right ascension and declination, local altitude and azimuth, celestial latitudes and longitudes, distances from the sun and earth, angular size, brightness, and rise and set times. It also supplies sidereal time, twilight times, Julian day numbers, equation of time values, phase of the moon and planets, elongations from the sun and orbital elements. All the basic astronomical information, including heliocentric and geocentric, is provided in a well organized format. AstroView (A-VIEW) Collins, Bill $0 is the best public domain astronomy program we've seen. It lets you select a longitude and latitude from a map of the world and then view the planets and stars on each horizon or overhead. Unlike similar programs, this one is fast. Cluster White, David E. $10 simulates stellar mechanics, i.e. the effect of gravity on the motion of objects in space. It can be used to model the motion of stars in a cluster, or of planets around a sun. Several sample data files are supplied. CGA, EGA, VGA, and Herc are supported. Mars-EGA Nohr, Paul and Rowe, Basil H. $10 will give a simulated view of mars and the moon. You can change the time and date of the simulation, change the eyepiece or animate the view. Optics Westwater, Bob $? computes various parameters of a reflecting telescope. Planets Puhl, Larry $? computes information relating to the position, distance, magnitude, orbit view, skyview, etc for the major planets, four minor planets or halley's comet on a specified date and time. Also, orbital data for any desired planet or comet can be entered and saved in a disk file. Skyview and orbital views can show forward or backward motion. The moons for each planet can be displayed. Sunrise calculates the time of sunrise and sunset. -------------------------------- END OF SMALL PROGRAMS DISK #0667 -------------------------------- ACE (AstroSoft Computerized Ephemeris) Gardner, Jerry and Morrison, Martin $? #27047/798 [2 disks] is a general-purpose astronomy software package consisting of three separate parts: Part I of ACE performs the most needed astronomical calculations, involving the sun, the moon, the planets, eclipses, astrophotography exposures, mean sidereal time and Julian Day, precession of coordinates, phases of the moon, equinoxes and solstices, Galilean satellites of Jupiter, perpetual calendar, and Polaris.

Stellar Evolution 2.0 Greaney, Edward $20 #20148 is an interactive tutorial on stellar evolution. It was designed for high school level astronomy. Each stage of a star's life is discussed with both graphical and pictorial illustrations. The program has a few bugs in it, but is still a worthwhile presentation. Requires VGA, a mouse and 2.5 MB of hard disk space. Universe Analyzer Mahin, Mark $15-$35 #1924 purports to show scientifically that the universe must have been created rather than having been formed by random happenings. The basis for this conclusion is a calculation showing that the odds of all circumstances being just right so that the universe could form are extremely small. This whole exercise seems to swing on the "obvious fact" that if the odds of something happening are 1 in a googolplex, then it can be dismissed. However, while that may be a fair assumption in everyday life, in the context of infinite time in which the universe could well exist, every possible circumstance, no matter how remote, would eventually occur. In other words, who's to say that a googolplex of failed universes did not occur prior to the development of this one? Nevertheless, if you have not been exposed to the scientific theories underlying the calculations in this program, you may find reading about them in the program to be interesting. ----------------- 1331 Maps, Travel Small Programs Disk ----------------- DXCC displays the longitude and latitude of specified cities, states or countries. Designed primarily for ham radio operators, others may find it useful too. Gulf29 $0 are Mideast map files to be used with WORLD29, the popular computer-globe program that lets you zoom in on any area of the world you wish.

A special "Match" feature of Tracker allows you to compare the current storm with up to 20 of the most similar historic storms from the data base and overlay their tracks on the map. A hard disk and EGA compatible video are required. An 80x87 is helpful, but not required. World29 2.9g Lloyd, Robert L. ASP $10 #27226/142 is the ultimate "globe". The most fun part of World is pointing with the cursor keys and seeing increasingly detailed maps (down to about the size of a state). This is the screen you see at computer shows, but World has a lot more: flexible latitude and longitude entry, five level location display, a city finder, distance calculator, state and national capitals locator, hurricane tracking, unified Yemen and Germany maps, and more. The program supports EGA/VGA (otherwise CGA is required). Note that NumLock must be on and you must use the number pad to move the pointer, not the cursor keys. James J. Schmidt, Sunnyvale, CA: "The program hangs after drawing a map and aborts with an error message." PsL: After starting the program, it asks if you want to use an overlay file and shows "Y/N", when we entered "Y" we received the error message after the map was drawn. When we just pressed Return instead of Y or N, the program drew the map and did not abort with an error message. WorldVu 1.2 Technical Solutions $15 #12177 is a world atlas which allows you to find and display places from around the world. The magnification level can be set to view the world as one might see it from space or zoom in to examine the detailed surface characteristics. Rotation of the earth can be animated.

Current temperatures are charted against historical data on a full-year or quarterly basis with moving average smoothing. Up to 140 years of daily temperatures can be processed, with temperatures from -40 to +110 degrees for up to 220 localities. Requires EGA. Weather Forecaster/Database 3.5g Shamrock Software $20 #12187 forecasts the weather for the next 24 hours based on your input of barometric pressure, temperature, relative humidity, cloud conditions, and wind direction. It will also convert between Celsius and Fahrenheit, determine the wind chill factor, help predict the snow level, display low and high temperatures for all 50 states, relative humidity and cloud height. The program also has a national humidity map, information on equipment that includes how to make some of them at home and a few weather facts. MapMaker #0120 draws maps. It produces two common forms of quantitative maps; CHOROPLETH (Area Coloring) and GRADUATED CIRCLE. Choropleth maps display statistical variables by using a sequence of colors (maximum of 3). Circle maps represent data with proportionately-sized circles. MapMaker can also save and later recall screen images without going through the create process. Requires BOTH monochrome and color monitors and cards. Merlin 1.5f Parker, T.M. $31 #4334 is a comprehensive hurricane/tropical storm tracking tool for the 1993 hurricane season. It builds advisory reports from user input, great circle calculations, linear and curvi-linear regression modeling, and neural network decisions. What-if scenarios can be generated by choosing an alternate tracking location from a pop-up menu. A tracking map provides a graphic representation of the current storm. Historical information about past storms is also included. ]]]]]
