The program uses planets and a small archive of stars: "Achern","Acrux","Agena","Aldebaran","Alnair","Altair","Ankaa","Antares","Arneb","Arturo","Betelgeus e", "Canopus","Capella","castore","Deneb","Fomalaut","Fornacis","Kiffa","Mizar","Peacock","Phact"," Polare", "Procione","Regolo","Rigel","Sirius","Spica","Vega". These stars can be used to find geographic direction.
In Demo version the user will be able to select only the first six stars.
Moreover the program gives topocentric coordinates (Azimuth and Altitude) and times of rise, transit and set of the celestial object (for the Moon, when the event occur the next day, it will be displayed by ****).
At the bottom, on the left, you can see the azimuth and altitude values. The button AA allows to display Right Ascension and Declination rather than Azimuth and Altitude and vice versa (text on button will change in RD: when it displays AA you see Azimuth and Altitude values, when you read RD, the program shows Right Ascension and Declination values).
On the right side you can see (graphically, by a small cross) the altitude of the object respect on the horizon (the minimum on the vertical axis is -90°, the maximum is +90°, the step is 30°).
The LST (Local Sidereal Time - that is the Right Ascension that transits on celestial meridian of the observer) will be display in LST frame.
Requested data
Once the procedure has been started, the user can modify the date, longitude, latitude and local time. It is also possible to take in account daylight-savings time. The values related to the current date and time will be displayed.
Date
By date-control you can insert any permit date .
Local time
The time is the local civil time of the time zone of the site. If you want to consider daylight-saving time you have to check DST box.
If your Time Zone is not equal to Longitude Time Zone of your geographical site you can use TZ field.
See the documentation to find correct time zone limits.
Latitude
There are no limits about the latitude of the site (of course when the user latitude is 90N or 90S the result can be strange).
You can insert values between 90 South and 90 North. In demo version the program will only use integer part (degrees) of the value.
Longitude
It is possible to insert value between 180 West and 180 East.
The program allows to store geographical coordinates by the option Store geo coordinates. In this case the program will also store DST and TZ data.
Equinoxes and Solstices
This command displays time of the March and September Equinoxes and June and December Solstices, for any year. In Demo version the program will only calculate values for current year.
Earth's Surface
It is possible to calculate the distance between two points on the Earth's surface. Moreover the program allows to know other geographical information about the parallel of any latitude: distance from Earth's center, the radius of the parallel, the length of one degree of longitude and latitude, the linear velocity, the radius of curvature of the Earth's meridian at any latitude.
Your shadow
Do you want to know the length of your shadow and other information? This function calculates the direction and the length of your shadow at any time (if the Sun is above the horizon) moreover it displays the time when the shadow lies on your meridian (towards north or south depend on your latitude and Sun position) and the times when it is equal to your height. In Demo version the program will calculate the shadow for integer value of the time (without minutes).
Geo Sites
It is possible to use geographical coordinates of 388 towns in the world. The user can choose the site: the program will automatically use the corresponding coordinates (not in Demo version).
Moon's Phases
The program calculates the phases of the Moon near the inserted date. It gives the time of the Full Moon, New Moon, First quarter and Last quarter. In Demo version the program will only calculate values for current month.
Easter
By this command the program calculates the Easter date for any year.
